Description
Wolfspeed’s 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.
