CGH40045F

Overview

The CGH40045F is a gallium nitride (GaN) high-electron mobility transistor (HEMT) designed for broadband RF and microwave applications. Operating from a 28 V rail, it delivers up to 4 GHz operation with 16 dB small signal gain at 2.0 GHz and 12 dB at 4.0 GHz. The device provides 55 W typical saturated power output (PSAT) and achieves 55% efficiency at PSAT. It features a flange package (440193), supports large signal models for ADS and MWO, and withstands 10:1 output mismatch stress.
