General Notes:
1. The PSES-3 series of phase shifters provides continuously variable phase shift across a range of 0° to 180° with the application of a control
voltage of 0 to +30V.
2. Each phase shifter element employs lumped element quadrature hybrids with matched pairs of varactor 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 each
quadrature hybrid. Similar Phase Shifters are available in a variety of packages, including catalog models in flatpacks and Meri-Pacs.
3. All Merrimac phase shifters are designed for high reliability and can be supplied screened to meet specific military and space applications. 15Feb96
