Hi everyone,
Quick question—do RF diplexers work both ways? I know they can be used to split one signal into two different frequency bands, or combine two signals into one. But if we feed two signals into the low and high ports, can we just assume they'll combine properly and come out the common port without any issues?

I ask this because diplexers are passive, reciprocal devices, and they should ( it seems to me ) work bidirectionally.

Thanks in advance!

 

Yes, they do.
