Product Summary

The RF9810 is a Quad Band EDGE +TD-SCDMA Multi-Mode Transmit Module with the capability to support both GSM/GPRS/Linear EDGE (GSM850/EGSM900/DCS1800/PCS1900) and TD-SCDMA (1880MHz to 1920MHz and 2010MHz to 2025MHz) B34/39 frequency bands. The RF9810 continues to build upon RFMDs leading patented PowerStar® Architecture to include such features as a Power Flattening Circuit, VRAMP Filtering, VBATT Tracking, EDGE Low Power Mode. And, RFMD has integrated TD-SCDMA functionality into the RF9810, so it can be used as the transmit module in 3.2V, 50W GSM/TD-SCDMA dual-mode cellular equipment. The RF9810 module includes a multi-function CMOS controller, GaAs HBT power amplifier, and pHEMT front end antenna switch.
