Description
Alpha’s high power, 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’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
a specialized high power 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.
