RF7183 Quad-Band TX, Dual-Band RX GSM, GPRS Transmit Module
The RF7183 is a quad-band (GSM850/EGSM900/DCS1800/PCS1900) GSM/GPRS Class 12-compliant transmit module with integrated baluns and filtering for improved ISM rejection. The four RX ports are 100W impedance and provide a differential output to allow flexibility when interfacing with various transceiver configurations. The RF7183 features RFMD’s latest integrated power-flattening circuit, which significantly reduces current and power varation into load mismatch. Additionally, a VBATT tracking feature is incorporated to maintain switching performance as supply voltage decreases. The RF7183 integrates an ESD filter to provide excellent ESD protection at the antenna port.
