CGH40120F
120 W, RF Power GaN HEMT
Cree’s CGH40120F is an unmatched, gallium nitride (GaN) high
electron mobility transistor (HEMT). The CGH40120F, operating
from a 28 volt rail, offers a general purpose, broadband solution
to a variety of RF and microwave applications. GaN HEMTs offer
high efciency, high gain and wide bandwidth capabilities making
the CGH40120F ideal for linear and compressed amplier circuits.
The transistor is available in a ange package.
