Variable Gain amplifier
17 to 27 GHz
functional Diagram
The HmC997lC4 is a Gaas mmiC pHemT analog
variable gain amplifier and / or driver amplifier which
operates between 17 and 27 GHz. ideal for microwave
radio applications, the amplifier provides up to 20.5 db
of gain, output p1db of up to +24 dbm, and up to +31
dbm of output ip3 at maximum gain, while requiring
only 170 ma from a +5V supply. a gain control voltage
(Vctrl) is provided to allow variable gain control up to 15
db. Gain flatness is excellent making the HmC997lC4
ideal for eW, eCm and radar applications. The
HmC997lC4 is housed in a roHS compliant 4 x 4 mm
ceramic Qfn leadless package and is compatible with
high volume surface mount manufacturing.
