PSM-2 Series PHASE SHIFTERS, MANUAL 10 to 500 MHz / 0 to 90 / 10% Bandwidth / Multi-Turn Adjustment, High Resolution Manual Units PRINCIPAL SPECIFICATIONS GENERAL SPECIFICATIONS Model Number Center Frequency, fo, MHz Usable Bandwidth PSM-2-***B 10 to 500 fo ± 5% For complete Model Number replace *** with desired Center Frequency, fo in MHz. Typical Performance Phase Shift Range 90° min. @ fo Insertion Loss: 1.5 dB max. Impedance: 50 Ω nom. VSWR: 1.6:1 max. Screw Drive: Multi-Turn Turns for maximum phase shift: 10 MHz to 125 MHz: 32 turns nom. 125 MHz to 500 MHz: 18 turns nom. CW Power: 0.5 Watts max. Weight, nominal: 2 oz (58 g) Operating Temp: -- 55° to +85°C 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. Package Outline 15Feb96 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.
