Description
Alpha’s three-stage reactively-matched 27–31 GHz
GaAs MMIC driver amplifier has typical small signal gain
of 19 dB with a typical P
1 dB
of 16 dBm at 28 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 a
conductive epoxy die attach process. All chips are
screened for gain, output power and S-parameters prior
to shipment for guaranteed performance. Designed for
27–31 GHz LMDS and digital radio bands.
Dimensions indicated in mm.
All DC (V) pads are 0.1 x 0.1 mm and RF In, Out pads are 0.07 mm wide.
