摘要： A tunable radio frequency (RF) filter is provided. The RF filter comprises a signal transmission path having an input and an output, a plurality of resonant elements disposed along the signal transmission path between the input and the output, and a plurality of non-resonant elements coupling the resonant elements together. The resonant elements are coupled together to form a stop band having a plurality of transmission zeroes corresponding to respective frequencies of the resonant elements, and at least one sub-band between the transmission zeroes. The non-resonant elements comprise at least one variable non-resonant element for selectively introducing at least one reflection zero within the stop band to create a pass band in one of the sub-bands(s). The variable non-resonant element(s) may be configured for displacing the reflection zero(es) along the stop band to selectively move the pass band within the one sub-band or within selected ones of the sub-bands.

摘要： A resonator and filter including the resonator is disclosed. The resonator (100) includes an open conductive loop (100) with folded transmission line segments (124, 134) extending from the adjacent ends of the loop. Of each transmission line segment, the portion emanating from the respective end of the loop is positioned generally along-side the corresponding portion of the other transmission line segment. That is, the two transmission line segments are folded away from each other. The resonator can be generally elongated in shape, with the loop at one end of the long axis and the transmission line segments at the other. The transmission line segments occupy a footprint (W2) that is not substantially greater than the width of the loop (W1). The filter includes multiple resonators of the invention, each resonator being coupled to at least another or the resonators. The resonators can be positioned in a side-by-side fashion, with the long axes of the resonators parallel or anti-parallel to one another.

摘要： A filter is composed of plural resonators formed on one surface of a dielectric substrate and a ground plane formed on the other surface. A resonant frequency of each resonator is accurately measured individually and independently from other resonators. Other resonators not selected for measurement are all short-circuited or covered with a conductive member to shift their resonant frequency to a region that does not interfere with the resonant frequency of the resonator under measurement. Also, a coupling coefficient of an arbitrary pair of resonators is accurately measured under no interference from other resonators in the similar manner.
