RF7203 3V WCDMA Band 3/4 Linear PA Module
The RF7203 is a high-power, high-efficiency, linear power amplifier designed for use as the final RF amplifier in 3V, 50Ω WCDMA mobile cellular equipment and spread-spectrum systems. This PA is developed for UMTS Band 3 which operates in the transmit frequency band from 1710MHz to 1785MHz. The RF7203 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 RF7203 is HSPA+ compliant and is assembled in a 10-pin, 3mm x 3mm module.
