The designer can select a discrete, three-stage PA configuration with the MRF7P20040H as the final amplifier, or the MD7IC2050N IC (which includes the driver and final amplifier stages) in a two-stage PA configuration.
The new amplifiers' high linearity minimizes additional signal distortion for repeater applications when used in final amplifier stages, and reduces backoff power requirements to minimize distortion from high PAR (peak to average ratio) signals in 3G/4G mobile base stations.
When employed in a final amplifier application at 28 V, it is designed to deliver a gain of 28 dB, ALT1 of -47 dBc and ALT2 of -49 dBc (6-carrier TD-SCDMA signal) from 2010 MHz to 2025 MHz at an output power of 35 dBm.
