I was just quoting the sales flyer. I agree that the bandpass curve has the typical "knee" shaped bandpass curve instead of the bell shaped curve for what I would call a bandpass duplexer. The only real application that I can see for these duplexers would be a mobile installation that is operating in the full-duplex mode. It's interesting that they picked 52 and 53MHz on the plot, maybe they were targeting the ham market?
