I'm not going to pretend I understand why the 5G filter works, but it does.

Simple enough: block 5G frequencies so that if there is a 5G transmitter in your area its signal doesn't overload the input of your receiver (or an amplifier). Wanted signals can't get through if the 5G signal is driving inputs into saturation.

I've not heard of 5G being so strong it overloads the input of the receiver, but it is technically possible. Aerial amps are more of a problem because they have much more gain, and even if their input is not overloaded the 5G can clip in the gain stage. That is the more common issue with 4G and 5G.

My explanation was deliberately simplistic, the difference between saturating an input and clipping in the gain stage is splitting hairs and not relevant and either place a limit on the maximum signal to remain linear.

Just an aside regarding strong 5G signals but unrelated to this thread, my wife and I each have Motorola G84 G5 mobiles and when using the camera outdoors, airplane mode has to be selected in order to take a picture. Research shows 5G strength is the problem.
