This board contains a low and high pass filters. The use of this duplexer is, for example, to split a multiband antenna (2m+70cm) into two outputs: 2m and 70cm - two TRXs, or separate connectors on one TRX. It is also possible to combine two antennas (2m+70cm) into one coax cable and split the bands down at the TRX.
