2. Insertion loss increases with clockwise rotation of knob.
3. Dimensions in inches over millimeters.
4. Dial is uncalibrated.
General Notes:
1. The PS-5 series of manual phase shifters covers the 5 to 200 MHz frequency
range providing continuously variable phase shift 0° to 360°. This is
accomplished by cascading two 180° shifters for a total of 360°. A lock is
provided to avoid unintentionally changing the intended setting.
2. These models employ a pair of lumped element quadrature hybrids with
matched pairs of L-C networks acting as sliding short circuits on the outputs.
The electrical length of the shorts effectively delays the reflected signal which
appears at the isolated ports of the quad hybrids.
3. Merrimac Phase Shifters are designed for high reliability, and can be supplied
screened for specific applications.
