RF7401

3V W-CDMA BAND 1 LINEAR PA MODULE

The RF7401 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 1 which operates in the 1920MHz to 1980MHz 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, 3mmx3mm module.
