FC7113

Future Communications Integrated circuit Inc. FC7113 Power Amplifier Module for CDMA/AMPS DESCRIPTION FC7113 is a high-power, high-efficiency power amplifier module for CDMA/AMPS wireless handsets. It consists of a two-stage amplifier, 50ohm matching network for both input and output ports, and bias control circuitry. One of the most important features of FC7113, the fixed bias mode operation, which eliminates the need for mode change between low-power and high– power/high-gain mode, provides excellent performance up to 31-dBm output power. This advantage also makes it possible to carry out one step calibration in any handsets with very low idle current. It is assembled in a 3-mm x 3mm package without any passive component in it. This lead-free package provides excellent electrical stability and low thermal resistance. This FC7113 is manufactured with an advanced InGaP HBT MMIC process.
