General Notes:
1. The PSM-4E series of Phase Shifters provides continuously variable phase shift across the range of 0° to 180°. An additional 180° phase shift
can be switched in to provide a total range of 360°.
2. To realize variable phase shifts, these models employ a lumped element quadrature hybrid with a matched pair of L-C 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. Merrimac phase shifters are designed for high reliability and can be supplied screened for specific applications.
