General Notes:
1. The PSE and PSEM series of phase shifters provide
continuous voltage controlled phase adjustment with the
application of 0 to +15V. On PSE/PSEM-3 models the
full range is 180°. On PSE/PSEM-4 models the range is
extended to 360° by cascading two similar 180° phase
shifters in one package. All models may be supplied with
optional linearized transfer characteristics.
2. Merrimac phase shifters are designed for high
reliability and can be supplied screened to meet specific
military and space applications.
