RF9810

The RF9810 is a highly integrated Quad Band EDGE + TD-SCDMA Multi-Mode Transmit Module designed by RF Micro Devices. It supports both GSM/GPRS/Linear EDGE (GSM850/EGSM900/DCS1800/PCS1900) and TD-SCDMA (1880MHz to 1920MHz and 2010MHz to 2025MHz) B34/39 frequency bands.

This module features RFMD's patented PowerStar Architecture, including a Power Flattening Circuit, VRAMP Filtering, and VBATT Tracking. It operates with a supply voltage range of -0.3 to +6.0 V and has an input RF power rating of +10 dBm. The module is designed for use in 3.2V, 50W GSM/TD-SCDMA dual-mode cellular equipment.

The RF9810 integrates a multi-function CMOS controller, a GaAs HBT power amplifier, and a pHEMT front-end antenna switch. The amplifier devices are manufactured on RFMD's Advanced Gallium Arsenide Heterojunction Bipolar Transistor (GaAs HBT) Process, capable of operating in saturated mode for GMSK or linear mode for EDGE 8PSK and TD-SCDMA signaling. The RF ports are 50W matched, and the antenna port includes robust 8kV ESD protection circuitry.

Packaged in DIP, the RF9810 operates within a temperature range of -30 to +85 ℃. Its design simplifies GSM/TD-SCDMA dual-mode handset and data card development by eliminating the need for complex control loop design, output RF spectrum optimization, harmonic filtering, and component matching, thereby improving product time to market.
