Analog and digital phase shifters are an integration of either Varactor or PIN diodes with passive circuitry. These units are continuously variable analog or converted to digital control or a true digital component that is switched from state-to-state. Operating frequency ranges span from 200 MHz to 22 GHz, in up to 9:1 bandwidths, and made available with 500 ƞSec or 1.0 µSec switching speeds. Narrowband models available from 22.0 GHz to 35.0 GHz with 10% bandwidth.
