Abstract
A duplexer/diplexer comprising at least a transmission branch and a reception branch. The transmission branch and the reception branch are modularly connected by shielding, and are arranged such that the two branches are matched to an identical value of resistance (50 Ohms) in their passband, and offer broadband high-impedance in the stopband of the band neighboring the passband. As a result, all three ports of the duplexer/diplexer are matched to the same value of resistance given parallel connection of the two branches.
