General Notes:
1. The PSM-2D-2250 provides continuous phase
adjustment of microwave signals with a compact package
equipped with SMA connectors.
2. The phase shifter employs microstrip quadrature
hybrids with dual capacitor tuned LC 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. Similar phase shifters designed for lower frequencies
are available in a variety of connectorized packages.
Merrimac also makes electronically tuned models in
flatpacks, surface mount and Meri-Pac™ PC mounts .
