| MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MRFIC2004/D The MRFIC Line 900 MHz Driver and Ramp The MRFIC2004 is an integrated Driver and Ramp designed for transmitters operating in the 800 MHz to 1.0 GHz frequency range. The Ramp is an integrator which can be used for burst control for TDD/TDMA systems. The Driver uses a cascode configuration for high gain and reverse isolation. A power down control is provided to minimize current drain with minimum recovery/turnon time. Also, an on-board inverter is included to provide complementary control for an antenna switch, such as the MRFIC2003. The design utilizes Motorola's advanced MOSAIC 3 silicon bipolar RF process to yield superior performance in a cost effective monolithic device. Applications for the MRFIC2004 include CT1 and CT2 cordless telephones, GSM, remote controls, video and audio short range links, low cost cellular radios, and ISM band transmitters. * * * * * * * * Small Signal Gain = 21.5 dB (Typ) Small Signal Gain Control = 34 dB (Typ) Po 1.0 dB = -1.0 dBm (Typ) On Board Ramp for Burst Control Power Down Supply Current = 0.7 mA (Typ) Low Operating Supply Voltage (2.7 to 4.0 Volts) Input/Output VSWR Insensitive to Gain Control Order MRFIC2004R2 for Tape and Reel.

Ramp Voltage versus Rise & Fall Time MOTOROLA RF DEVICE DATA MRFIC2004 5 APPLICATIONS INFORMATION DESIGN PHILOSOPHY The MRFIC2004 was designed as a support IC for a CT2 chip-set. The other chips making up the chip-set are the MRFIC2001 downconverter, the MRFIC2002 transmit mixer, the MRFIC2003 antenna switch and the MRFIC2006 PA. A complete CT2 front-end solution requires a ramp for burst control, an inverter for complementary antenna switch control and gain control (or an attenuator) for the transmitter low power mode. In order to keep the other chips in the chip-set relatively general purpose, yet provide the system designer with an easily controlled solution, these functions were combined with a driver amplifier into one IC, the MRFIC2004. THEORY OF OPERATION The driver is a cascode design that exits the IC opencollector. Impedance matching must be done externally. Since the output requires a bias inductor and DC blocking capacitor, the output can be matched with these two elements. To keep the driver unconditionally stable, it is recommended that a 300 - 400 ohm resistor be placed in parallel with the bias inductor as close to the IC as possible. Since the output impedance of the driver by itself is very high, the resistor sets the output impedance. The input can be matched with a series inductor followed by a shunt capacitor. Alternatively, a series transmission line followed by a shunt capacitor can be used. A DC block is also required on the input. Gain control is provided to meet the CT2 low power mode requirement. The CT2 Common Air Interface specification requires the transmitter to be capable of dropping the output power by 16 4.0 dB. Although the driver has 34 dB of small signal gain control, it can be reduced by ad- ding a resistor in series with the gain control pin. The value of the resistor depends on the logic levels being used and the amount of gain compression after the driver. Also, the amount of gain control is a function of the driver input power level. The input power should be kept less than -10 dBm to allow for sufficient gain control to achieve the low power mode. The gain control can also be used for PA output power trimming. However, this is not an efficient method. The ramp is an integrator which is used to slow down the driver and PA turn-on and turn-off times to reduce AM splatter. By applying a pulse waveform to the input, a linear ramp waveform is created at the output which is then applied to the current mirrors of the driver and PA. An external integrating capacitor is used so that the rise/fall time can be programmed externally. A minimum value of 2.0 - 2.4 nF is needed to meet the CT2 Common Air Interface splatter specification. For non-TDD/TDMA systems the ramp reverts to an enable/disable function. The inverter is CMOS/TTL compatible and was included to provide complementary control for an antenna switch such as the MRFIC2003. By applying the receiver enable control line, RXEN, to the inverter the inverse RXEN will be created. RXEN and RXEN can then be used to control the MRFIC2003 antenna switch.
