Product Description

The RF7115 is a high-power, high-efficiency transmit module containing

RFMD’s Power Star© integrated power control, integrated pHEMT front end

antenna switch and harmonic filtering functionality. All of which combine to pro-

vide for best in class harmonic emission control and RX and TX insertion loss.

The device is self-contained with 50Ω input and output terminals with no

matching components required. The integrated power control function based

on RFMD’s patented Power Star© control is incorporated, eliminating the need

for directional couplers, detector diodes, power control ASIC’s, and other power

control circuitry; this allows the module to be driven directly from the DAC out-

put. The device is designed for use as the final portion of the transmit chain in

GSM850, EGSM900, DCS and PCS GMSK and eliminates the need for PA to

antenna switch module matching. On-board power control provides over 70dB

control range. The integrated antenna switch allows true quad band TX and RX

functionality. Built-in current limiter option may be utilized to minimize power

variation in mismatch condition.
