Typical Performance Data
General Notes:
1. The PSM-2A series provides continuous phase shift in
the range of 0擄 to 90擄 using a multi-turn adjustment screw.
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.

NOTES:
1. Tolerance on 3 place decimals
.020(.51) except as noted.
2. Insertion phase increases with clockwise rotation of screw.
3. Dimensions in inches over millimeters.
