Product Description
The RF3237 is a quad-band (GSM850/EGSM900/DCS1800/PCS1900)
GSM/GPRS Class 12-compliant transmit module with four transmit/receive ports
for UMTS use that also serve as GSM Rx ports. This transmit module builds upon
RFMD's leading PowerStar® integrated power control technology, SOI (silicon-on-
insulator) switch technology, and integrated transmit filtering for best-in-class har-
monic 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/UMTS handset
and eliminates the need for a PA-to-antenna switch module matching network. The
device provides 50 matched input and output ports requiring no external match-
ing components.
The RF3237 features RFMD's latest integrated power-flattening circuit, which signif-
icantly reduces current and power variation into load mismatch. Additionally, a
VBATT tracking feature is incorporated to maintain switching performance as supply
voltage decreases. The RF3237 also integrates an ESD filter to provide excellent
ESD protection at the antenna port.
