RF3285 Dual-Band GSM850/PCS1900 Transmit Module
Product Details The RF3285 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 W 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 GSM850 / PCS1900 and eliminates the need for PA-to-antenna switch module matching. On-board power control provides over 70 dB control range. The integrated antenna switch allows true dual-band TX and RX functionality. This device also features RFMD’s latest integrated power flattening circuit which significantly reduces current and power variation into load mismatch.
