详细描述
The RF7206 is a high-power, high-efficiency, linear power amplifier designed for use as the final RF amplifier in 3 V, 50 W W-CDMA mobile cellular equipment and spread-spectrum systems. This PA is developed for UMTS Band 2 which operates in the 1850 MHz to 1910 MHz frequency band. The RF7206 has 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 an integrated directional coupler which eliminates the need for an external discrete coupler at the output. The RF7206 is fully HSDPA-compliant and is assembled in a 10-pin, 3 mm x 3 mm module.
