详细描述
The RF7182D 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 RF7182D features RFMD’s latest integrated power-flattening circuit, which significantly reduces current and power variation into load mismatch. The RF7182D also integrates an ESD filter to provide excellent ESD protection at the antenna port. The RF7182D is designed to provide maximum efficiency at rated POUT.
