RF7177 Dual-Band EGSM900/DCS1800 TxM with Integrated Received SAW Filters  

The RF7177 is a dual-band (EGSM900/DCS1800) GSM/GPRS Class 12 compliant Transmit Module with integrated Receive SAW Filters. This transmit module is the next step of integration to include a multi-function CMOS controller, GaAs HBT power amplifier, pHEMT front-end antenna switch and Rx SAW filters all in one package for a true single front end solution. The two Rx ports are 150Ω impedance and provide a differential output to allow flexibility when interfacing with various transceiver configurations. The RF7177 continues to builds upon RFMD’s leading patented PowerStar® Architecture to include such features as Power Flattening Circuit, VRAMP Filtering, and VBATT Tracking. The highly integrated transmit module simplifies the phone 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 cellular phone systems. The Tx 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.
