GENERAL SPECIFICATIONS Phase Shift Range: 90° min. Insertion Loss: 1.5 dB max. Impedance: 50 Ω nom. VSWR: 1.6:1 max. Screw Drive: Multi-turn (insertion phase increases with clockwise rotation) Turns for max. Phase Shift 10 MHz to 125 MHz: 32 turns nom. 100 MHz to 500 MHz: 18 turns nom. CW Power: 0.5 Watts max. Package: PC Plug-In Weight, nominal: 1.1 oz. (31 g) Operating Temp: -- 55° to +85°C General Notes: 1. The PSS-2 series provides continuously variable phase shift across the range of 0 ° to 90 ° using a precision, multi-turn screw adjustment. 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 and Meri-Pacs. 15Feb96 NOTES: 1. Tolerance on 3 place decimals ±.020(.51) except as noted. 2. Dimensions in inches over millimeters. 3. All unmarked pins are internally ground.
