HJF-A-500 HJF-A-500 HJSF-A-500 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.
