Package Outline *Unit may be operated at +10 dBm in reduced control range of 1.5 - 15 V. (+30 V no damage) OPTIONAL SPECIFICATIONS NOTES: 1. Tolerance on 3 place decimals .020(.51) except as noted. 2. Dimensions in inches over millimeters. Lower Frequencies: Flatpack Version: see PSEM series see PEF series General Notes: 1. The PSAM series of voltage controlled analog phase shifters controls phase shift using a voltage of 0 to +30V. On PSAM-3 models the full range is from 0 to 180 and on PSAM-4 this is extended to 0 to 360 by cascading two similar 180 phase shifters. 2. Each phase shifter element employs FilmbridTM quadrature hybrids with matched pairs of varactor tuned LC networks acting as sliding short circuits on the outputs. The electrical length of short effectively delays the reflected signal which appears at the isolated port of each quadrature hybrid. 3. Similar phase shifters are available in a variety of packages including catalog models in flatpacks and Meri-Pacs. 4. Merrimac phase shifters are designed for high reliability and can be supplied screened to meet specific military and space applications. 15Feb96 F rf t e if r to c n a tM ERRI AC /41 Faifel Pl,W estCal el,NJ,07006 / 973o ur h r n o ma in o t c M ri d . dw l 5751300 /FAX 973- 0531 575- |
