Product Description
The RF7167 is a dual band (GSM850/PCS1900) GSM/GPRS Class 12-compliant transmit mod-
ule with two symmetrical receive ports. This transmit module builds upon RFMD’s leading
power amplifier with PowerStar® integrated power control technology, pHEMT switch technol-
ogy, and integrated transmit filtering for best-in-class harmonic performance. The results are
high performance, reduced solution size, and ease of implementation simplifies transmitter
design. The device is designed for use as the final portion of the transmitter section in a
GSM850/PCS1900 handset and eliminates the need for PA-to-antenna switch module match-
ing network. The device provides 50Ω matched input and output ports, thereby requiring no
external matching components.
The RF7167 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 perfromance as supply voltage decreases.The RF7167 also
integrates an ESD filter to provide excellent ESD protection at the antenna port. The RF7167 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 Ctrl0 selects band of operation.
20 GPCTRL0 Control pin that together with Ctrl1 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.
