general description the max2351/max2354/max2358/max2359/max2530/ max2531/max2537/max2538 family of single- and multi- band lna/mixer ics is optimized for cdma, gsm, and tdma applications in both cellular and pcs bands. in addition, the max2530/max2531/max2537/max2538 ics feature a gps lna/mixer signal path for e911 and traveler assistance applications. the cellular and pcs signals can be routed to either if port. for example, one if port can be connected to an if filter with 30khz bandwidth, while the other port can drive an if filter with a wider bandwidth. the gps band has its own if port. to optimize dynamic range at minimum current, the max2351/max2354/ma x2358/max2359/ max2530/ max2531 /max2537 /max2538 implement multiple lna and mixer states, including high gain/high linearity, high gain/low linearity, midgain, low gain, and ultra-low gain. in high-gain/high-linearity mode, the high-ip3 lna mini- mizes desensitization in the presence of a large interfer- ing signal. for the other gain states, the lna current is reduced to improve standby time. each band is imple- mented with a separate mixer to optimize performance for the specific band, and each mixer provides multiple lin- earity modes to optimize linearity and current consump- tion. the ultra-low gain mode operates with very little current, which results in significant power savings because the handset typically spends most of its time in this mode. applications triple-band, quadruple-mode pcs/cellular handsets single-band handsets e911 and traveler assistance through gps gsm/tdma cellular phones features ? eliminate up to 35 external components ? low lna noise figure pcs: 1.2db cellular: 0.9db gps: 1.0db ? no external gps vco required ? no interstage gps saw filter required ? triple band, quadruple mode ? ultra-low current: <10ma average in cdma phones ? small 28-pin qfn package (5mm ? 5mm) max2351/4/8/9/max2530/1/7/8 quadruple-mode pcs/cellular/gps lna/mixers ________________________________________________________________ maxim integrated products 1 28 if output mux 27 26 21 20 19 1 2 3 18 4 17 16 5 6 15 2 7 25 24 23 22 89 10 11 12 13 14 1.5 max2538 g1 glna_in gnd clna_in plna_in clna_out gif- gif+ ifo- ifo+ v cc lo_out buffen plna_out band if_sel if1- if1+ pmix_in cmix_in glna_out g2 gmix_in mode bias pll lo_in shdn pin configurations ordering information 19-2487; rev 3; 1/04 for pricing, delivery, and ordering information, please contact maxim/dallas direct! at 1-888-629-4642, or visit maxim? website at www.maxim-ic.com. part temp range pin-package max2351 eti -40 c to +85 c 28 thin qfn-ep* max2354 eti -40 c to +85 c 28 thin qfn-ep* max2358 eti -40 c to +85 c 28 thin qfn-ep* max2359 eti -40 c to +85 c 28 thin qfn-ep* max2530 eti -40 c to +85 c 28 thin qfn-ep* max2531 eti -40 c to +85 c 28 thin qfn-ep* max2537 eti -40 c to +85 c 28 thin qfn-ep* max2538 eti -40 c to +85 c 28 thin qfn-ep* * ep = exposed pad. pin configurations continued at end of data sheet. selector guide part cell pcs gps cell vco pcs vco max2351 ?? input internal doubler max2354 ? input max2358 ?? internal divider input max2359 ? input max2530 ??? input input max2531 input internal doubler max2537 ? internal divider input max2538 ??? internal divider input

detailed description signal paths and operation modes the max2351/max2354/max2358/max2359/max2530/ max2531/max2537/max2538 have multiple rf signal paths. the cellular signal path has five modes of opera- tion using a 4-gain-mode lna and a 3-gain-mode mixer. similarly, the pcs signal path has four modes of opera- tion made up of a 2-gain-mode lna and a 3-gain-mode mixer. the cellular and pcs mixer? if output can be routed to either the if0 or if1 port. the gps signal path consists of a single-mode gps, lna, and mixer, which has a dedicated if output port. tables 1 and 2 summa- rize the modes of operation. low-noise amplifiers the max2351/max2358/max2530/max2531/max2538 incorporate three lna signal paths for the cellular, pcs, and gps bands. using maxim? latest advanced bicmos sige process, these lnas deliver 1db noise figure for cellular, pcs, and gps bands. the cellular band lnas have four modes of operation: high gain/ high linearity (hghl), high gain/low linearity (hgll), midgain (mg), and low gain (lg). the pcs band lnas have two modes of operation: high gain/high linearity and low gain. the gps lna has only one mode. the band input selects the frequency band. the g1, g2, and mode pins are logic inputs that control the lna modes (see table 2). use hghl mode when high max2351/4/8/9/max2530/1/7/8 quadruple-mode pcs/cellular/gps lna/mixers _______________________________________________________________________________________ 9 pin description (continued) pin max2351 max2358 max2354 max2359 max2530 max2531 max2538 max2537 name function 16 16 16 16 16 lo_out pcs and cellular lo output. output frequency is equal to mixer lo frequency. internally matched with dc-blocking capacitor. if not used, connect pin to ground or leave open. 17 17 17 17 17 v cc 2.7v to 3.3v supply pin. connect a 100pf bypass capacitor as close as possible to the pin. 18, 19 18, 19 18, 19 18, 19 18, 19 if0+, if0- differential if output port 0. requires a pullup inductor and a dc-blocking capacitor at each pin, which can be used as part of the matching network. if not used, connect pins to v cc . 20, 21 20, 21 gif+, gif- gps if output. requires a pullup inductor and a dc-blocking capacitor at each pin, which can be used as part of the matching network. if not used, connect pins to v cc . 22, 23 22, 23 22, 23 22, 23 22, 23 if1+, if1- differential if output port 1. requires a pullup inductor and a dc-blocking capacitor at each pin, which can be used as part of the matching network. if not used, connect pins to v cc . 24 24 24 24 cmix_in cellular mixer input. internally matched to 50 ? , including an on-chip dc-blocking capacitor. 25 25 25 pmix_in pcs mixer input. internally matched to 50 ? . requires a dc- blocking capacitor. 26 26 26 26 26 if_sel if select logic input. logic low selects if0 port, and logic high selects if1 port. 27 27 27 band band logic input. see table 2 for details. 28 28 28 plna_out pcs lna output. requires a pullup inductor and a dc- blocking capacitor, which can be used as part of the matching network. ep ep ep ep ep exposed exposed pad. rf and dc ground.
max2351/4/8/9/max2530/1/7/8 lna linearity is required for cross-modulation suppres- sion. use hgll mode when the transmitter is off and cross-modulation is not a concern. the lnas are designed to minimize input vswr when changing modes. use low-gain mode for receiving large signals and when high sensitivity is not required. the cellular band provides an additional gain mode (mg) for improved ip3 margin in cdma medium-level interfer- ence condition. downconverters the downconverters in these devices are double- balanced mixers. the cellular and pcs mixers have three gain modes: high linearity, low linearity, and low gain. the cellular and pcs mixers can route the if sig- nal to either if0 or if1 port. if_sel = low routes the if signal to if0 port; if_sel = high routes the if signal to if1 port. the gps mixer has only one mode, and it has a dedicated if port (table 2). all mixer inputs include on-chip matching networks to reduce the external com- ponent count. lo generation table 3 shows the options for the lo generation. the on-chip lo divider or multiplier allows triple-band oper- ation with a single vco. the max2351 and max2531 have an lo multiplier that doubles the cellular band vco for pcs band operation. conversely, the max2358, max2537, and max2538 include an lo divider that divides the pcs vco frequency down to cellular frequency band. the gps lo is generated by a fractional frequency scaler, which enables a single vco for operation in all three bands. the max2530 is designed for operation with a dual-band vco. the pll buffer output is provided for phase-locked loop operation. the pll pin serves two functions: rf output signal for phase-locked loop operation and logic input to enable or disable this buffer. a logic high applied to this pin enables the pll buffer; a logic low disables the buffer. a buffered lo output is provided to drive a transmit upconverter. it is controlled by the buffen input. for time-division duplex applications, the buffer is available to drive the transmitter even when the rest of the chip is shut down. the port is internally ac-coupled, so a dc- blocking capacitor is not required. bias control the bias control input (bias pin) controls the ic bias current. typically, connect a 20k ? resistor to ground for normal operation. smaller bias resistor values increase the supply current and linearity. applications information cascaded lna/mixer performance the lna and mixer design optimizes cascaded perfor- mance in all gain and linearity modes. in high-gain/high- linearity mode, both the lna and mixer have low noise figure, high gain, and high linearity. in this mode, the lna has extra-high linearity for superior cross-modula- tion suppression. the high-gain/low-linearity mode is used when the transmitter is off and cross-modulation is not a concern. in the ultra-low-gain mode, the received signal is strong enough that sensitivity is not the limiting factor. this mode focuses on minimizing supply current. tables 4, 5, 6 summarize the cascaded performance. lnas the lna inputs require external matching networks to optimize gain, linearity, noise figure, and return loss. a simple lc match is sufficient as shown in the typical application circuit . the cellular and gps lna outputs are internally matched. the pcs lna output requires an inductor pullup to v cc and a series capacitor as external matching elements. table 7, 8, 9 show the s- parameters for each lna. tables 13, 14, 15 show lna noise parameters. mixers all mixer inputs are internally matched. the gps and pcs mixer inputs require a dc-blocking capacitor; the cellular mixer does not. all if outputs must be induc- tively pulled up to v cc . the inductive pullup may be used as part of the matching network. because the dif- ferential if output port is high impedance, a load resis- tor is typically used to ease the matching and establish the gain. a 3.3k ? resistor is recommended for if0 and if1, and 8.2k ? for the gif port. the equivalent parallel rc impedance of the if ports is typically 12.2k ? in par- allel with 0.75pf. tables 10, 11, 12 show s-parameters for the mixer input points. quadruple-mode pcs/cellular/gps lna/mixers 10 ______________________________________________________________________________________ abbreviation mode hghl high gain/high linearity hgll high gain/low linearity mg midgain lg low gain ulg ultra-low gain hl high linearity ll low linearity table 1. abbreviation for lna and mixer modes
gps interstage the gps lna and mixer include on-chip resonant tanks that can be used instead of a saw filter for image sup- pression. these tanks are coupled by an external l-c network between pins 8 and 10 as shown in the typical application circuit . layout considerations keep rf signal lines as short as possible to minimize losses and radiation. use controlled impedance on all high-frequency traces. use high-q (>40) components for the lna input-matching circuit to achieve the lowest possible noise figure. at the mixer outputs, keep the differential signal lines together and of equal length to ensure signal balance. for proper operation, solder the exposed paddle evenly to the ground plane. use abun- dant ground vias between rf traces to minimize unde- sired coupling. max2351/4/8/9/max2530/1/7/8 quadruple-mode pcs/cellular/gps lna/mixers ______________________________________________________________________________________ 11 band operation mode lna mixer if port g2 g1 mode band hghl hghl hl if0 or if1 0010 hgll hgll ll if0 or if1 0000 mg mg hl if0 or if1 0 1 x 0 lg lg ll if0 or if1 1 1 x 0 cellular ulg lg lg if0 or if1 1 0 x 0 hghl hghl hl if0 or if1 0011 lg lg ll if0 or if1 1 1 x 1 pcs ulg lg lg if0 or if1 1 0 x 1 gps* gps gps gps gif 0001 table 2. modes of operation * max2530/max2531/max2537/max2538 only. x = don? care. part vco frequency cellular lo frequency pcs lo frequency gps lo frequency max2351 cell band vco f vco 2 x f vco max2354 cell band vco f vco max2358 pcs band vco 0.5 x f vco f vco max2359 pcs band vco f vco max2530 cell and pcs dual-band vco f vco f vco (2/3) f vco max2531 cell band vco f vco 2 x f vco (4/3) f vco max2537 pcs band vco 0.5 x f vco (2/3) f vco max2538 pcs band vco 0.5 x f vco f vco (2/3) f vco table 3. lo frequency plan
