The QPD0050 from Qorvo is a single stage unmatched GaN RF power transistor that operates from DC to 3.6 GHz. It provides an output power of 75 watts with a gain of 19.4 dB and an efficiency of 77.9%. This transistor requires 48 volts of power supply and is available in a surface mount plastic package that measures 6.6 x 7.7 mm. The QPD0050 can be used in a Doherty architecture for the final stage of a base station power amplifier for small cell, microcell, and active antenna systems. The QPD0050 can also be used as a driver in power amplifiers for macrocell base stations.
