General Notes:
1. The PSS-2 series provides continuously variable phase shift across the range
of 0° to 90° using a precision, multi-turn screw adjustment.
2. These phase shifters employ lumped element quadrature hybrids with
capacitor tuned LC networks acting as sliding short circuits on the outputs. The
electrical length of the short effectively delays the reflected signal which appears
at the isolated port of the quadrature hybrid.
3. Similar phase shifters are available in a variety of connectorized packages as
well as electronically tuned models in flatpacks and Meri-Pacs.
