General Notes:

1. The PSAM series of voltage controlled analog phase shifters controls phase shift using a voltage of 0 to +30V. On PSAM-3 models the full

range is from 0° to 180° and on PSAM-4 this is extended to 0° to 360° by cascading two similar 180° phase shifters.

2. Each phase shifter element employs Filmbrid™ quadrature hybrids with matched pairs of varactor tuned LC networks acting as sliding short

circuits on the outputs. The electrical length of short effectively delays the reflected signal which appears at the isolated port of each quadrature

hybrid.

3. Similar phase shifters are available in a variety of packages including catalog models in flatpacks and Meri-Pacs.

4. Merrimac phase shifters are designed for high reliability and can be supplied screened to meet specific military and space applications.
