详细描述
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 portion 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 significantly
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.
