詳細描述,RFMD’s RF7202 is a high-power, high-efficiency, dual-band, linear power amplifier designed for use as final amplification stages in 3V, 50?W-CDMA mobile cellular equipment and spread-spectrum systems. This PA is developed for UMTS Bands 2 and 5 which operates in the transmit frequency band from 1850?MHz to 1910?MHz and 824?MHz to 849?MHz, respectively. The RF7202 uses two digital control pins to select one of three power modes to optimize performance and current drain at lower power levels. The part also has one integrated directional coupler output which eliminates the need for an external discrete coupler for each band. The RF7202 is fully HSDPA and HSPA+ compliant and is assembled on a 14-pin, 4?mm x 5?mm laminate module.,特點,Dual-Band 2/5 UMTS PA,HSDPA and HSPA+ Compliant,Low Voltage Positive Bias Supply (3.0V to 4.35V),High Efficiency Operation: ????41% at POUT=+28.5dBm (Band 2) ????41% at POUT=+28.0dBm (Band 5) ????19% at POUT=+19.0dBm (without DC/DC converter),Low Quiescent Current in Low Power Mode: 16mA,Internal Voltage Regulator Eliminates the Need for External Reference Voltage (VREF),Common VMODE Control Lines Between Bands,3-Mode Power States for Each Band with Digital Control Interface,Supports DC/DC Converter Operation (VCC Pin),Integrated Power Coupler,Integrated Blocking and Collector Decoupling Caps
