(31 g) operating temp: -- 55 to +85c general notes: 1. the pss-2b series consists of pc mountable phase shifters with continuous multi-turn adjustment from 0 to at least 90. 2. this series employs 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 that 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 surface mounts. 15feb96 notes: 1. tolerance on 3 place decimals .010(.25) except as noted. 2. dimensions in inches over millimeters. 3. all unmarked pins are internally ground.
