Typical Performance Data
General Notes:
1. The PS-4 series mechanically adjusts phase
continuously from 0° to 180°. A mechanical switch inserts
an additional 180° switched shift for a total of range of
0° to 360°. A lock is included to avoid unintentionally
changing the selected setting.
2. 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 which
appears at the isolated port of the quadrature hybrid.
3. Merrimac phase shifters can be supplied screened for
specific applications.
