RF3231 Dual-Band GSM900/DCS1800 Transmit Module with WCDMA Port 

The RF3231 is a dual band (EGSM900/DCS1800) GSM/GPRS Class 12 compliant transmit module with two symmetrical receive ports and one high linearity WCDMA port. This transmit module builds upon RFMD’s leading power amplifier with PowerStar® integrated power control technology, pHEMT switch technology, and integrated transmit filtering for best-in-class harmonic performance. The results are high performance, reduced solution size, and ease of implementation. The device is designed for use as the final portion of the transmitter section in a GSM900/DCS1800/WCDMA handset and eliminates the need for a PA-to-antenna switch module matching network. The device provides 50 ohm matched input and output ports requiring no external matching components. The RF3231 features RFMD’s latest integrated power-flattening circuit, which significantly reduces current and power variation into load mismatch. Additionally, a VBATT tracking feature is incorporated to maintain switching performance as supply voltage decreases. The RF3231 also integrates an ESD filter to provide excellent ESD protection at the antenna port. The RF3231 is designed to provide maximum efficiency at rated POUT.
