RF7401 3V WCDMA 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, 50Ω WCDMA mobile cellular 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 externaldiscrete coupler at the output. The RF7401 is fully HSDPA-compliant and is assembled in a 10-pin, 3mm x 3mm module.
