BROAD BAND HYBRID JUNCTION
5 to 1000 MHz / High Isolation / Low Insertion / Hi-Rel / Hermetic Pkg Symmetrical And Assymetrical
TECHNICAL DESCRIPTION / APPLICATION
1. The HJF-A Series of assymetrical hybrid junctions uses lumped element circuits to provide very compact and light weight solutions to a
variety of signal processing functions. Among these are applications in beamformers, quadrapole networks and hybrid added amplifiers.
a)
Power division with phase shift:
Signals applied to the delta (∆) port, or E-arm, will divide equally between output ports 1 and
2 (colinear 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 (colinear arms) and be in phase.
2. The
HJSF-A Series, is fully symmetrical,
i.e. insertion phase of E-1 equals that of H-1 allowing its use in beamforming applications, or
any application requiring vector addition.
3. 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.
