Product Description
The RF7166 is a dual band (EGSM900/DCS1800) GSM/GPRS Class 12 compliant
transmit module with two symmetrical receive 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, a reduced solution
size, and ease of implementation. The device is designed for use as the final por-
tion of the transmitter section in a GSM900/DCS1800 handset and eliminates the
need for PA-to-antenna switch module matching network. The device provides 50Ω
matched input and output ports requiring no external matching components.
The RF7166 features RFMD’s latest integrated power-flattening circuit, which signif-
icantly reduces current and power variation into load mismatch. The RF7166 also
integrates an ESD filter to provide excellent ESD protection at the antenna port. The
RF7166 is designed to provide maximum efficiency at rated POUT.

VBATT
Power supply for the module. This should be connected to the battery ter-
minal using as wide a trace as possible.
19 GPCTRL1 Control pin that together with GpCtrl0 selects band of operation.
20 GPCTRL0 Control pin that together with GpCtrl1 selects band of operation.
21 TX ENABLE This signal enables the PA module for operation with a logic high. The
switch is put in TX mode determined by GpCtrl0 and GpCtrl1.
