Description
Alpha's single balanced fundamental mixer IC has a typical
conversion loss of 8 dB at an LO power level as low as
12 dBm over the band 2333 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 or
solder die attach process. All chips are screened for DC
diode parameters and lot samples are RF measured to
guarantee performance
