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.
