RFMD’s new RF3235 and RF3237RFMD’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 RF3237 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, SOI (silicon-on-insulator) 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. 50Ω matched input and output ports require no external matching components.

Features
  • High Efficiency at Rated POUT
  • VBATT = 3.5V
  • GSM850/EGSM900 = 43%
  • DCS1800/PCS1900 = 36%
  • No External DC Blocking Needed on TRx Ports
  • 0.6db LB, 0.8dB HB TRx Insertion Loss for 3G Efficiency and Improved Rx Sensitivity
  • Four (RF3237) to Six (RF3235) High Linearity TRx Ports
  • >35dB Isolation for Most Port Combinations
Applications
  • Single through Quad-Band UMTS Handsets and Connected Devices Including TDSCDMA and CDMA
  • GSM850/EGSM900/DCS1800/PCS1900 Products
  • 3V Multimode Mobile Applications
  • GPRS Class 12 Compliant
These products are currently available in production quantities.
