Alpha’s ring hybrid GaAs Schottky diode mixer has a
typical conversion loss of 6.0 dB at an LO power level as
low as 9 dBm over the band 32–37 GHz. The chip uses
Alpha’s proven Schottky diode technology, and is based
upon MBE layers for the highest uniformity and
repeatability. The diodes 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
DC diode parameters and lot samples are RF measured
to guarantee performance.
