Abstract: A microwave filter has a housing defining an inner cavity. A first resonator is positioned in a first portion of the inner cavity. A second resonator is positioned in a second portion of the inner cavity. A third resonator is positioned in a third portion of the inner cavity. The first resonator and the third resonator are cross-coupled via an iris. The second resonator is elongated and is coupled to the first resonator and the third resonator. The resulting microwave filter has a frequency response having a transmission zero in the lower stopband. A high-pass filter is realized without the use of a cross-coupling probe.
