6.7 900MHz Splitter/Combiner (05-002602)
6.7.1 Description
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 will be
terminated with an appropriate 50Ω load.
Being passive devices, the splitters should have an extremely long operational life and require
no maintenance. Should a unit be suspect, it is usually most time efficient to replace the whole
module rather than attempt repair or re-tuning.
