Hi, I've got some questions about how the quarter wave cavity duplexer works in this configuration. From what I've read the cavities need to be connected together with 1/4 wavelength sections of cable. I'm not sure what the purpose of 1/2 cabling is. I'm told that its to transform the low impedance, but I'm not sure where. Also I thought the inputs to the receiver, transmitter and the cavities are all 50 ohms, so I'm not sure how the 1/4 wave cables would transform the impedance anyways.
thanks
thanks
