DC to 85 GHz High Performance Components

Digital Controlled Phase Shifters

Pulsar's Digital Controlled Phase shifters utilize PIN diodes and delay lines to produce the necessary phase requirements. These digital phase shifters use switched lines to obtain temperature stable phase shift. The phase is specified at the center frequency ± 3.0% and is proportional to frequency over the entire band.
