7.2 Tx Hybrid Coupler (05-000101)
7.2.1 Description
The Hybrid 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.
