Product Description
The RF7225 is a high-power, high-efficiency, linear power amplifier
designed for use as the final RF amplifier in 3V, 50 W-CDMA mobile cel-
lular equipment and spread-spectrum systems. This PA is developed for
UMTS Band 5 which operates in the 824MHz to 849MHz frequency band.
The RF7225 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 RF7225 is fully
HSDPA and HSPA+ compliant and is assembled in a 10-pin, 3mmx3mm
module.
