Description
Alpha’s three-stage reactively-matched Ka band GaAs
MMIC amplifier has a typical P
1 dB
of 19 dBm with 17 dB
associated gain over the band 37–39 GHz. The chip uses
Alpha’s proven 0.25
µm
MESFET technology, and is
based upon MBE layers and electron beam lithography
for the highest uniformity and repeatability. The FETs
employ surface passivation to ensure a rugged, reliable
part with through-substrate via holes and gold-based
backside metallization to facilitate an epoxy die attach
process. All chips are screened for small signal
S-parameters and power characteristics prior to shipment
for guaranteed performance. A broad range of
applications exist in both the high reliability and
commercial areas where power and gain are required.
