详细说明： The RF7168 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-inclass 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 GSM900/DCS1800 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 RF7168 features RFMD’s latest integrated power-flattening circuit, which significantly reduces current and power variation into load mismatch. The RF7168 also integrates an ESD filter to provide excellent ESD protection at the antenna port. ...展开收缩
