General Notes:
1. The PEF series of high frequency, voltage controlled phase
shifters combines the latest microstrip and lumped element
technologies to provide very high performance in a space
saving package.
2. With a center frequency of up to 1500 MHz, these units
extend the frequency range of the long established PSEF
series which cover the 10 to 500 MHz band.
3. These phase shifters are suitable for systems requiring
automatic phase control, closed loop networks and steering of
electronically scanned antennas.
4. Merrimac Phase Shifters are designed for high reliability, and
can be supplied screened to meet military and space
applications.
