All unmarked pins are internally ground. 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 ForfurtherinformationcontactM ERRIM AC /41 Fairfield Pl.,W estCaldw ell,NJ,07006 / 973-575-1300 /FAX 973-575-0531
