General Notes:
1. The PSEF-3E series of phase shifters provides continuously variable phase shift across a range of 0
°
to 180
°
with the application of a control
voltage of 0 to +15V. Similar phase shifters are available in a variety of other packages.
2. These units are designed for high reliability and can be supplied screened to meet specific military and space applications.
