Product Description
Applications
The RF3283 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. All of which combine to provide for best in class
harmonic emission control and RX and TX insertion loss. The device is self-con-
tained with 50Ω input and output terminals with no matching components required.
The integrated power control function based on RFMD’s patented PowerStar™ con-
trol 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 output. The device is designed for use as the final por-
tion 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 con-
trol provides over 70dB control range. The integrated antenna switch allows true
dual-band TX and RX functionality.
