详细描述
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 RFMD’s 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, 50Ω 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. The amplifier devices are manufactured on RFMD’s Advance Gallium Arsenide Heterojunction Bipolar Transistor (GaAs HBT) Process, which is designed to operate either in saturated mode for GMSK or linear mode for EDGE 8 PSK and TD-SCDMA signaling. The highly integrated EDGE + TD-SCDMA transmit module simplifies GSM/TD-SCDMA dual-mode handset and data card design by eliminating the need for complicated control loop design, output RF spectrum (ORFS) optimization, harmonic filtering, and component matching, all of which combine to provide best in class RF performance, solution size, and ease of implementation for GSM/TD-SCDMA dual-mode cellular phone and data card systems. The RF ports are 50Ω matched and the antenna port includes ESD protection circuitry which meets the stringent 8kV industry standards requiring no additional components. All of these eliminated factors help to improve the customer’s product time to market.
