Dimensions marked with * apply only at body. Typical HJF-A-200 Performance General Notes: 1. The HJF-A series of four port hybrid junctions uses lumped element circuits to provide a variety of signal processing functions. Among these are: a) Power division with phase shift: Signals applied to the delta () port, or E-arm, will divide equally between output ports 1 and 2 (co-linear arms) and be 180 out of phase. b) Power division with no phase shift: Signals applied to the sum () port, or H-arm, will divide equally between output ports 1 and 2 (co-linear arms) and be in phase. c) Vector addition: Simultaneous application of signals to both E and H arms results in their vector addition to one co-linear port and vector subtraction at the other. Correction for the phase difference between E and H paths to the co-linear ports must be made . This phase equalization may be applied externally or factory installed within the unit at additional cost. 2. All units comply with MIL-P-23971 and can be supplied screened for compliance with additional specifications for military and aerospace applications requiring the highest reliability. 22Feb96 For further information contact MERRIMAC / 41 Fairfield Pl., West Caldwell, NJ, 07006 / 973-575-1300 / FAX 973-575-0531 |
