RF3705 3V W-CDMA Band 5/8 Linear PA Module
The RF3705 is a high-power, high-efficiency, linear power amplifier designed for use as the final RF amplifier in 3 V, 50 Ω W-CDMA mobile cellular equipment and spread-spectrum systems. This PA is developed for UMTS Bands 5 and 8 which operate in the 824 MHz to 915 MHz frequency band. The RF3705 has an integrated directional coupler which eliminates the need for an external discrete coupler at the output.
