RF7205 3V W-CDMA Band 1/5 Dual Band PA Module

The RF7205 is a high-power, high-efficiency, dual-band, linear power amplifier designed for use as final amplification stages in 3V, 50 Ohm WCDMA mobile cellular equipment and spread-spectrum systems. This PA is developed for UMTS Bands 1 and 5 which operates in the transmit frequency bands from 1920MHz to 1980MHz and 824MHz to 849MHz, respectively. The RF7205 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 RF7205 is fully HSDPA compliant and is assembled on a 14-pin, 4mmx5mm laminate module. .
