描述 Description

Qorvo's RF7245 is a high-power, high-efficiency, linear power amplifier designed for use as the final RF amplifier in 3V, 50W WCDMA mobile cellular equipment and spread-spectrum systems. This PA is developed for UMTS Band 5 which operates in the 824MHz to 849MHz frequency band. The RF7245 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 RF7245 meets the spectral linearity requirements of High Speed Downlink Packet Access (HSDPA), High Speed Uplink Packet Access (HSUPA), and Long Term Evolution (LTE) data transmission and is assembled in a 10-pin, 3mm x 3mm module.
