Description
Skyworks' SP4T 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 Skyworks' 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 for DC diode breakdown voltage, turn-on voltage
and RF parameters on selected paths.
