the duplexer , is two band pass filters to combine the TX and RX to the antenna , and provide attenuation from both in the other band

the diplexer used to combine the output of two duplexes , it is always used in multiband phones

I think both of them should be called "双工器“,to avoid confusion,I call them in English.
