Family of Transmit Modules for 3G Entry Phones Expanded

Mon, 03/01/2010 - 7:38am
RF Micro Devices, Inc. has added four new products to its portfolio of 3G transmit modules. The RF3230, RF3231, RF3232, and RF3171 are designed to accelerate the implementation of 3G entry-level feature phones supporting one-to-two bands of WCDMA and two-to-four bands of GSM/GPRS (also referred to as WGPRS). Each new transmit module (TxM) features a GSM/GPRS power amplifier (PA) and an integrated pHEMT switch to support stringent 3G linearity requirements, providing a highly integrated, low cost alternative to discrete RF front end implementations. RFMD's RF3231 and RF3232 are optimized to support Infineon as well as other leading open-market 3G chipset suppliers. The RF3231 is a dual-band GSM/GPRS TxM with one low-loss wideband transmit/receive (TRx) port and two interchangeable GSM Rx ports. The RF3231 also features an integrated switch, integrated harmonic filtering and RFMD's patented PowerStar® integrated power control technology. The RF3232 shares a feature set with the RF3231 and increases functionality with one additional wideband TRx port. The RF3230 is a quad-band TxM with two low-loss wideband TRx ports and four interchangeable GSM Rx ports. The RF3171 adds Large Signal Polar EDGE capability to the lineup and is optimized to support Qualcomm and ST-Ericsson 3G chipsets.
