RF3232

The RF3232 is a quad band (GSM850/EGSM900/DCS1800/PCS1900) GSM/GPRS Class 12 compliant transmit module with two symmetrical receive ports and two high linearity UMTS ports. 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 GSM850/EGSM900/DCS1800/PCS1900 and UMTS handset and eliminates the need for a PA-to-antenna switch module matching network. The device provides 50Ω matched input and output ports requiring no external matching components. The RF3232 features RFMD’s latest integrated power-flattening circuit, which significantly reduces current and power variation into load mismatch. Additionally, a V BATT tracking feature is incorporated to maintain switching performance as supply voltage decreases. The RF3232 also integrates an ESD filter to provide excellent ESD protection at the antenna port.
