General Notes:
1. The PSM-2 series adjusts phase continuously with a
multi-turn screw from 0° to 90°.
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.
