Typical Performance
General Notes:
1. The PSM-3 phase shifters series provides
continuous phase adjustment across a range of
0擄 to 180擄 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.
