General Notes:

1. The PSM-2B and PSM-2C series provide

continuously variable phase adjustment using a

precision multi-turn screw from 0° to 90°. The

packages are compact and sturdy.

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, surface

mount packages and Meri-Pacs.
