    Qorvo's RF7849 is a high-power, high-efficiency, linear power amplifier designed for use as the final RF amplifier in 3V, 50F W-CDMA mobile cellular equipment and spread-spectrum systems. This PA is developed for UMTS Band 1 and Band 8 which operates in the 1920MHz to 1980MHz frequency band and 880MHz to 915MHz frequency band. The RF7849 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 RF7849 meets the spectral linearity requirements of High Speed Downlink Packet Access(HSDPA), High Speed Uplink Packet Access (HSUPA) and is assembled in a 20-pin, 4mmx4mm module.
