3G Switch Filter Modules

( 1 May 2009 )

RFMD's first available switch filter modules (SFMs), the RF1194 and the RF1195, are designed for use in multi-band, multimode 3G handsets. Both SFMs leverage RFMD's leadership in 3G front-ends, as well as proven GaAs manufacturing expertise, high volume cellular switch technology, and filter integration capabilities demonstrated in 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. Technical features of the RF1194 and RF1195 include pin-to-pin compatible, compact packages: 4.5mm x 4.5mm x 1.2mm; ESD protection; 8kV CD compliance through integrated ESD inductor; symmetrical GSM/GPRS/EDGE Rx ports with low insertion loss; symmetrical, high-linearity WCDMA/HSPA+ Tx/Rx ports; and enhanced VSWR performance.
