Maximum control voltage is 30 V. 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. 15Feb96 ForfurtherinformationcontactM ERRIM AC /41 Fairfield Pl.,W estCaldw ell,NJ,07006 / 973-575-1300 /FAX 973-575-0531 PSE & PSEM Series PHASE SHIFTERS 1 to 500 MHz / 0 to 180 and 0 to 360 / 10% Bandwidth / Voltage Variable / BNC & SMA Package Outline Notes: 1.
