The parts in RFMD’s new RF73xx series of high-power, high-efficiency linear power amplifiers are designed for use as the final amplification stage in 3 V, 50 Ω LTE mobile cellular equipment developed for E-UTRAN/LTE band operation. These parts are developed for 5 to 20 MHz LTE channel bandwidths.
Each has two digital control pins to select one of three power bias states to optimize performance and current drain at lower power levels. Each also has an integrated directional coupler which eliminates the need for an external discrete coupler at the output, and is assembled in a 10-pin, 3 mm x 3 mm x 0.8 mm module.
