PSM-2D-2250 PHASE SHIFTER, MANUAL 1 to 3 GHz / Continuous Phase Adjustment / Compact Package / SMA Connectors PRINCIPAL SPECIFICATIONS GENERAL SPECIFICATIONS Model Number Operating Band, GHz Minimum Phase Shift Range PSM-2D-2250 2.0 to 3.0 1.0 to 2.0 -- 90° -- 60° Typical Performance Insertion Loss: Loss Variation: Impedance: VSWR: Screw Drive: Turns for maximum shift: CW Power: Signal Connectors: Weight, nominal: Operating Temp: 1.5 dB typ. 1 dB typ. 50 Ω nom. 2.0:1 typ. Multi-Turn 16 turns nom. 0.5 Watts max SMA Female 1 oz (28 g) -- 55° to +85°C General Notes: 1. The PSM-2D-2250 provides continuous phase adjustment of microwave signals with a compact package equipped with SMA connectors. 2. The phase shifter employs microstrip quadrature hybrids with dual 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 designed for lower frequencies are available in a variety of connectorized packages. Merrimac also makes electronically tuned models in flatpacks, surface mount and Meri-Pac PC mounts . Package Outline 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. 15Feb96 ForfurtherinformationcontactM ERRIM AC /41 Fairfield Pl.,W estCaldw ell,NJ,07006 / 973-575-1300 /FAX 973-575-0531
