Description

Alpha’s single balanced GaAs Schottky diode mixer has

a typical conversion loss of 6.0 dB at an LO power level

as low as 8 dBm over the band 26–33 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.
