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. Package Outline NOTES: 1. Tolerance on 3 place decimals ±.020(.51) except as noted. 2. Insertion phase increases with clockwise rotation of screw. 3.
