General Notes:
1. The HJM series of hybrid junctions covers 1 to 500 MHz using
lumped element circuits to achieve high output port isolation and
excellent amplitude and phase balance.
2. The rugged housing is suitable for various terrestrial and
aerospace applications. A variety of packaging options is available.
3 These units comply with MIL-P-23971 and can be supplied
screened for compliance with additional specifications you
designate for high reliability applications.
