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.
