RFMD launches quad-band GSM/GPRS Tx modules with UMTS transmit/receive ports
RFMD’s new RF3235 and RF3237, paired with one or more discrete 3G power amplifiers such as RF722x or RF724x, enable best-in-class performance at the lowest total solution cost for 3G entry platforms.
RF3235 and 3237 are quad-band GSM/GPRS Class 12-compliant transmit modules. They include four (RF3237) to six (RF3235) UMTS transmit/receive ports that also serve as GSM Rx ports and are pin-to-pin compatible. Both build on RFMD's PowerStar® integrated power control technology, silicon-on-insulator (SOI) switch technology and integrated transmit filtering. These devices are designed for use as the final portion of the transmitter section in a GSM850/EGSM900/DCS1800/PCS1900/UMTS handset and eliminates the need for a PA-to-antenna switch module-matching network. 50 Ω matched input and output ports require no external matching components.
