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 (Σ) 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.
