5.1.2 2 & 4 Way UHF Splitters (05-002603 & 05-003401)
5.1.2.1 Description
The Splitter/Combiners used are UHF (300-500MHz) devices for accurately matching two or
more RF signals to single or multiple ports, whilst maintaining an accurate 50
Ω
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.
