Product Description
The RF7188 is a high-power, high-efficiency transmit module containing RFMD’s PowerStar™
integrated power control, integrated pHEMT front end antenna switch, and harmonic filtering
functionality. These features combine to provide for best-in-class harmonic emission control
and RX and TX insertion loss. The device is self-contained with 50 input and output terminals
with no matching components required. The integrated power control function based on
RFMD’s patented PowerStar™ control eliminates the need for directional couplers, detector
diodes, power control ASICs, and other power control circuitry. This allows the module to be
driven directly from the DAC output. The device is designed for use as the final portion of the
transmit chain in dual-band applications utilizing GSM900/DCS1800 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 dual-band TX and RX functionality.
The RF7188 features patented Load Switch functionality to provide less current consumption at
rated and ECTEL power levels
