RFMD’s new RF3235 and RF3237

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 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

About RF Cafe Copyright: 1996 - 2024 Webmaster: Kirt Blattenberger, BSEE - KB3UON RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
