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.
