General Notes:

1. The PSM-3 phase shifters series provides

continuous phase adjustment across a range of

0° to 180° using a precision screw adjustment.

2. Each unit in the series employs a lumped

element quadrature hybrid with a tuned LC

network acting as sliding short circuits on the

outputs to delay the reflected signal. Similar

phase shifters are available for higher

frequencies and wider bandwidths.

3. All models may be supplied screened for

compliance with specifications according to your

requirements.
