Product Description
The RF7115 is a high-power, high-efficiency transmit detector diodes, power control ASIC’s, 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 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 inte-
grated 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.
module containing RFMD’s Power Star© integrated power
control, integrated pHEMT front end antenna switch and
harmonic filtering functionality. All of which combine to
provide 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 func-
tion based on RFMD’s patented Power Star© control is
incorporated, eliminating the need for directional couplers,
