Appendix A - 4 Port Hybrid Insertion Losses
The 4 port hybrid provides isolation between opposite input ports and
between opposite output ports while providing a nominal 3.5 dB
splitting loss between adjacent inputs and outputs. Continuity is
bidirectional between adjacent Input and output ports as shown below.
Unused ports must be terminated in 50 Ohms to maintain hybrid balance
and optimum port return loss.
