[The RF3234 is a quad band (GSM850/EGSM900/DCS1800/PCS1900) GSM/GPRS Class 12
compliant transmit module with two symmetrical receive ports and one high linearity UMTS
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 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 RF3234 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 |
