Description
Alpha’s high isolation, single pole, double throw PIN diode
switch is a robust, high performance switch. It is ideal for
low loss, high isolation applications, particularly where 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 in each arm
and an on-chip bias network. Chips are measured on a
100% basis at 24, 28, and 30 GHz for insertion loss,
isolation, input and output return losses, and also at DC
for diode breakdown voltage and turn on voltage.
