| Future Communications Integrated circuit Inc. FC7103 Power Amplifier Module for CDMA/AMPS DESCRIPTION The FC7103 is a high power, high efficiency amplifier module for dual mode AMPS/CDMA wireless handset applications. The device is manufactured on an advanced InGaP HBT MMIC technology. Selectable bias modes that optimize efficiency for different output power levels, and a shutdown mode with low leakage current, serve to increase handset talk and standby time. The 10 Pin 4mm X 4mm surface mount package offers premium performance in a 50 system. FEATURES l Operating Frequency: 824~849MHz l High Efficiency n 56% AMPS, 42.5% CDMA l Very Low Quiescent Current: 32mA l Low Leakage Current in Shutdown Mode: < 3uA l Optimized for a 50 PIN CONFIGURATION APPLICATIONS l Single Mode CDMA Wireless Handsets l Dual Mode AMPS/CDMA Wireless Handsets FUNCTIONAL BLOCK DIAGRAM (X- ray Transparency Top View) For latest specifications, technical questions and additional product information, visit our website or e-mail us.

FC7103 Power Amplifier Module for CDMA/AMPS TURN ON SEQUENCE 1. 2. 3. Connect the amplifier to 50 RF input and output cables. Set the VCC1 and VCC2 supplies to +3.4V, and observed a current of 0mA. Set the VREF supply to +2.85V. Observe a current draw of approximately 85mA from the VCC supplies. (VMODE=0V, so the amplifier is in High Bias Mode) 4. Apply an RF signal and measure the RF performance. TURN OFF SEQUENCE 1. Turn off the RF signal. Do not disconnect the PA from the RF SMAs before first turn off the DC connections. 2. 3. Turn off the VREF and VMODE first and then turn off the VCC1 and VCC2. Disconnect the PAM from the test set up.
