Description
Alpha鈥檚 single pole, double 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鈥檚 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
a shunt PIN diode in each arm 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.
