6.3.3.3. Four Way Splitter/Combiner (05-003302)

The Splitter/Combiner used is a device for accurately matching two or more RF signals to single or

multiple ports, whilst maintaining an accurate 50Ω load to all inputs/outputs and ensuring that the

VSWR and insertion losses are kept to a minimum. Any unused ports should be terminated with an

appropriate 50 load.

6.3.3.4. 2 Way Power Splitter/ Combiner 80/20 (05-009903)

The power Splitter/Combiner is a device for accurately matching two or more RF signals to single or

multiple ports, whilst maintaining an accurate 50Ω load to all inputs/outputs and ensuring that the

VSWR, return and insertion losses are kept to a minimum. Any unused ports will be terminated with

an appropriate 50Ω load. Power devices such as these, typically give 10dB better output isolation

than low power equivalents – (important for splitters that feed antenna systems).
