rf7401 data sheet
The RF7401 is a high-power, high-efficiency, linear power amplifier
designed for use as the final RF amplifier in 3 V, 50 W-CDMA mobile cellular
equipment and spread-spectrum systems. This PA is developed for
UMTS Band 1 which operates in the 1920 MHz to 1980 MHz frequency
band. The RF7401 has a digital control pin which enables a low power
mode to reduce amplifier gain 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 RF7401 is fully HSDPA-compliant and
is assembled in a 10-pin, 3 mm x 3 mm module.
