CGHV40050
50 W, DC - 4.0 GHz, 50 V, GaN HEMT
Description
The CGHV40050 is an unmatched, gallium nitride (GaN) high electron mobility
transistor (HEMT). The CGHV40050, operating from a 50 volt rail, offers a general
purpose, broadband solution to a variety of RF and microwave applications up
to 4 GHz. The reference HPA design in the datasheet operates from 800 MHz to 2
GHz operation instantaneously. It is a demonstration amplifier to showcase the
CGHV40050’s high efficiency, high gain and wide bandwidth capabilities. The
device can be used for a range of applications from narrow band UHF, L and S
Band as well as multi-octave bandwidth amplifiers up to 4 GHz. The transistor is
available in a 2-lead flange and pill package.
