Description
Alpha’s high isolation, single pole, single throw PIN diode
switch is a robust, high performance switch. It is ideal for
low loss, high isolation applications, particularly where
broad bandwidths and high power handling is required.
The chip uses Alpha’s proven PIN 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. The GaAs MMIC employs
two shunt PIN diodes and an on-chip bias network. Chips
are measured on a 100% basis at 24, 28, 31 and 35 GHz
for insertion loss, isolation, input and output return losses,
and also at DC for diode breakdown voltage and turn on
voltage.
