Description
Alpha's double balanced sub-harmonic mixer IC has a
typical conversion loss of 10 dB at an LO power of 15 dBm
over the band 2632 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.
