Greensboro, NC — RF Micro Devices has announced the company's entry into the market for cellular switch filter modules. The first available switch filter modules (SFMs), the RF1194 and the RF1195, are designed for use in multi-band, multimode 3G handsets. Both SFMs leverage the company's leadership in 3G front ends, as well as its proven GaAs manufacturing expertise, high volume cellular switch technology and filter integration capabilities demonstrated in the POLARIS® radio solutions.
The RF1194 integrates a single-pole nine throw (SP9T) pHEMT switch, quad-band GSM/GPRS/EDGE transmit low-pass filtering (LPF) and four GSM/GPRS/EDGE receive (Rx) surface acoustic wave (SAW) filters, for implementation in a quad-band GSM/GPRS/EDGE, triple-band WCDMA/HSPA+ 3G multimode handset. With four symmetrical GSM/GPRS/EDGE Rx ports and three symmetrical, high-linearity WCDMA/HSPA+ Tx/Rx ports, the RF1194 simplifies the design of 3G multimode devices by providing a flexible, platform-capable front end solution.
The RF1195 integrates a single-pole ten throw (SP10T) pHEMT switch and builds upon the advantages of the RF1194's architecture by providing an additional high-linearity port for a total of four symmetrical WCDMA/HSPA+ Tx/Rx ports.
