DESCRIPTION
Millitech series PS3 and PS4 are multithrow PIN switches or PIN switch matrices
for 18 to 110 GHz applications. Standard
products and configurations are offered for
three and four-throw switches in a single
integral housing for most waveguide
bands.
Higher
level
switching
arrangements can be designed in single,
compact housing without cascading
individual SPDT or other switches. Integral
drivers for the switches can be
incorporated in the housing to minimize the
overall size. Logic and switching schemes
can be tailored to fit customer interface
requirements.
Typical insertion loss per stage of switching
ranges from 1.0 dB at 18 GHz to 2.70 dB at
110 GHz. Standard low loss switches have
switching time of 150 ns and 20 ns for fall
and rise time, respectively. A higher speed
version of these switches is offered with
slightly greater insertion loss. Switching time
for the high speed version is typically 2 ns.
Millitech also offers series PSP single-pole,
single-throw (SPST) switches, series PDT
single-pole, double-throw (SPDT) switches,
and series PSH high speed switches.

*1 - Higher isolation possible with increase in insertion loss.
*2 – Maximum bandwidth offered. Superior performance for narrower bandwidth.
*3 – Switching speed is driver dependent. See figure1 below for explanation of switching speeds.
