Abstract:
An inline microwave bandpass filter where cross coupling between non-adjacent resonators is realized by changing the orientation of selected resonators. The microwave bandpass filter includes a cavity and three or more resonators arranged in a row (or inline) in the cavity. At least one resonator has a different spatial orientation from at least one other resonator. For example, one or more of the resonators may be rotated 90 or 180 degrees with respect to one of the other resonators. This arrangement of resonators facilitates sequential coupling between pairs of adjacent resonators and cross coupling between at least one pair of non-adjacent resonators without the use of additional cross coupling structures such as dedicated coupling probes or extra cavities. One or more plates may be introduced between adjacent resonators to independently control the sequential and cross coupling.
