Product Description
The RF7176 is a quad-band (GSM850/EGSM900/DCS1800/PCS1900) 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, 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 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 RF7176 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 RF7176 also integrates an ESD filter to provide excellent ESD protection at the antenna
port.

Power Flattening and VBATT Tracking Circuit
The RF7176 has an integrated power flattening circuit that reduces the amount of current variation when a mismatch is
presented to the output of the PA. When a mismatch is presented to the output of the PA, its output impedance is varied
and could present a load that will increase output power. As the output power increases, so does current consumption.
The current consumption can become very high if not monitored and limited. The power flattening circuit is integrated onto
the CMOS controller and requires no input from the user.
Into a mismatch, the current varies as the phase changes. The power flattening circuit monitors current through an internal
sense resistor. As the current changes, the loop is adjusted in order to maintain current. The result is flatter power and
reduced current into mismatch.
The RF7176 also incorporates a VBATT tracking feature that eliminates the need for the transceiver/baseband to regulate the
ramping signal as the supply voltage decreases. The internal circuit monitors the supply voltage and adjusts the ramping
signal such that the switching spectrum is minimally impacted.
