The PSM-2A series provides continuous phase shift in the range of 0 to 90 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. Package Outline 22Feb96 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.
