General Notes:
1. The QHM-4R-G series covers 500
MHz to 26.5 GHz using an advanced
stripline design for high isolation and
low loss.
2. Signals applied to any port will split
equally between the opposite pair with
the adjacent port remaining isolated.
The phase relationship is 0° to the port
directly opposite and --90° to the port on
the diagonal.
3. These units comply with
MIL-P-23971 and can be supplied
screened for compliance with additional
specifications for military and space
applications requiring the highest
reliability.
