FC7103

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 Ω 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 Ω System 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.
