Hi Jim:
Interesting.? It seems that the weak (desired) signal is attenuated about 4dB while the strong signal is knocked down to the limiting level.? See:
The device makes use of circulators/isolators to maintain a reasonable VSWR.
I looked since a simple diode limiter does the same thing, except it knocks down all signals and has a high VSWR.
