5.6 3 Way Splitter/Combiner (05-003801)
5.6.1 Description
The 3 way Splitter/Combiner used is a ‘Zinger’ type design for accurately matching three
RF signals to a single port, whilst maintaining an accurate balance between ports, and
ensuring that the VSWR and insertion losses attain the best possible specification. They are
specialist passive devices and must be replaced in the unlikely event of failure.
