2. Dimensions in inches over mm.
General Notes:
1. The PLB & PLM series use a control voltage of 0 to +15V to vary relative phase
across a 180° range.
2. Each phase shifter element employs quadrature hybrids with matched pairs of
varactor tuned LC networks acting as sliding short circuits on the outputs. The
electrical length of this short circuit controls the delay in the reflected signal
appearing at the isolated port of each quadrature hybrid.
3. These units are suitable for high reliability and space applications.
