general description the max2664 and max2665 are ultra-compact lnas for vhf/uhf applications. these devices incorporate a broadband lna with an integrated bypass switch. the max2664 covers the uhf frequency range from 470mhz to 860mhz, and the max2665 covers the vhf frequency range from 75mhz to 230mhz. each device has a zero-power bypass mode for improved high-signal-level handling conditions. additionally, the output port is internally matched to 50 while a single external inductor is used to match the input port to 50. the max2664 and max2665 are available in a 4-bump (0.8mm x 0.8mm x 0.64mm), lead-free, wafer-level pack - age (wlp). applications smartphones/handsets mp3 players home audio/video portable navigation devices features uhf and vhf frequency range ? max2664: 470mhz to 860mhz ? max2665: 75mhz to 230mhz low noise figure ? max2664: 1.2db ? max2665: 1.1db high gain: 15db zero-power bypass mode single +2.4v to +3.5v supply voltage low current: 3.3ma small footprint: 0.8mm x 0.8mm thin profile: 0.64mm 19-5476; rev 1; 3/15 + denotes a lead(pb)-free/rohs-compliant package. part temp range pin-package max2664 ews+ -40oc to +85oc 4 wlp max2665 ews+ -40oc to +85oc 4 wlp rfin gnd rfout/ ctrl v cc a1 a2 b1 b2 + max2664max2665 top side view max2664/max2665 vhf/uhf low-noise amplifiers functional diagram ordering information evaluation kit available downloaded from: http:///

detailed description the max2664/max2665 are low-power lnas designed for vhf/uhf applications. the devices feature an internal lna bypass control mode for better linearity under high- input-signal power conditions. the devices are offered in a small wlp package. input and output matching only an inductor in series with a dc-blocking capaci - tor is needed to form the input-matching network. the typical application circuit shows the recommended input- matching network. these values are optimized for the best simultaneous gain, noise figure, and return loss per - formance. tables 1 and 2 list typical device s-parameter values. the devices integrate an on-chip 50 output- matching network, eliminating the need for external matching components. bump name function a1 gnd ground. connect to the pcb ground plane with minimal trace inductance. a2 v cc supply voltage. bypass to ground with a 1000pf capacitor as close as possible to the ic. b1 rfin rf input. requires an external matching inductor and dc-blocking capacitor. the nominal internal dc voltage is 750mv. b2 rfout/ctrl rf output and bypass control (see the applications information section). rfout is internally matched to 50? and incorporates an internal dc-blocking capacitor. wlp top view max2664max2665 rfin gnd rfout/ctrl v cc a1 a2 b1 b2 + max2664/max2665 vhf/uhf low-noise ampliiers www.maximintegrated.com maxim integrated 9 bump description bump coniguration downloaded from: http:///

active bypass mode control the devices rfout/ctrl pin is used to control the bypass mode of the lna. when set to logic-high through an external 1k resistor, the devices active mode is enabled. conversely, when connected to logic-low, the devices bypass mode is enabled. an external dc-blocking capacitor should be used to isolate the control function of this dual-purpose pin (see the typical application circuit ). applications information a properly designed pcb is essential to any rf micro - wave circuit. use controlled-impedance lines on all high-frequency inputs and outputs. bypass v cc with decoupling capacitors located close to the device. for long v cc lines, it might be necessary to add additional decoupling capaci - tors. locate these additional capacitors further away from the device package. proper grounding of the gnd pin is essential. if the pcb uses a topside rf ground, connect it directly to the gnd pin. for a board where the ground is not on the component layer, connect the gnd pin to the board with multiple vias close to the package. refer to www.maximintegrated.com for the max2664/ max2665 s-parameter download, max2664/max2665 ev kit schematic, gerbers, pads layout file, and bom information. table 4. max2665 typical noise parameters v cc = 2.7v, t a = +25oc, z 0 = 50 table 5. logic table * r n is normalized. frequency (mhz) fmin (db) | opt | opt angle r n * 60 0.911 0.1390 34.5 0.1241 90 0.928 0.1458 47.2 0.1240 120 0.940 0.1592 58.1 0.1237 150 0.949 0.1766 67.0 0.1233 180 0.958 0.1962 74.5 0.1227 210 0.967 0.2170 80.7 0.1221 240 0.975 0.2383 86.2 0.1213 rfout/ctrl mode high active low bypass package type package code outline no. land pattern no. 4 wlp w40a0+1 21-0480 max2664/max2665 vhf/uhf low-noise ampliiers www.maximintegrated.com maxim integrated 11 package information for the latest package outline information and land patterns (footprints), go to www.maximintegrated.com/packages . note that a +, #, or - in the package code indicates rohs status only. package drawings may show a different suffix character, but the drawing pertains to the package regardless of rohs status. chip information process: sige bicmos downloaded from: http:///
