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.
