The cross coupling mechanism between the second of the at least two combline type resonators with the first of at least two combline type resonators can be through a transmission line shorted on all ends of the at least two combline type resonators or by placing the first of at least one ring type resonator in a different layer or by keeping all of the at least two combline type resonators relatively straight and placing the first of at least one ring type resonator such that cross coupling occurs between the plurality of resonators by virtue of the proximity of all of the plurality of resonators.

摘要： This invention is a filter circuit having a filter element. A filter element (4) is a parallel resonator circuit including a pair of first resonator lines (19a) (19b) formed by a thick film forming technique and a pair of second resonator lines (20a) (20b). As the thickness of the pair of second resonator lines (20a) (20b) is significantly reduced, the impedance ratio between the pair of second resonator lines (20a) (20b) and the pair of first resonator lines (19a) (19b) is increased. Therefore, the length of these pairs of resonator lines (19a) (19b) (20a) (20b) is reduced and miniaturization of the filter element is realized.

摘要： A high-frequency circuit device includes a dielectric substrate. A planar conductor is provided on each of top and bottom surfaces of the dielectric substrate and a slot line is formed on the top surface. Also, undesired-wave propagation preventing circuits, each including multistage band-elimination filters, are provided on the top surface of the dielectric substrate, with the slot line therebetween. Each of the band-elimination filters includes two conductive lines and a resonator which is provided at a portion of one of the conductive lines and which includes two spiral lines. Accordingly, propagation of an undesired wave of the band whose center is the resonance frequency of the resonator can be prevented.

摘要： A method for the design of tunable filters is disclosed. MEMS switches are used to alter the resonant frequency of one or more resonators. By tuning the resonant frequency of the resonators, the filter's characteristics also are tuned. Furthermore, MEMS switches are used to alter the input coupling, including direct input coupling and capacitive input coupling. Direct input coupling is altered by using the MEMS switches to select different input connection points. Capacitive input coupling is altered by using MEMS switches to add additional input capacitance to an input coupling capacitor.

摘要： A millimeter wave module includes a silicon substrate with first and second cavityes formed by anisotropic etching on the silicon substrate, and a glass substrate having a microstrip filter pattern and microbumps for connecting the glass substrate to the silicon substrate. A filter is provided using an air layer as a dielectric disposed in the first cavity. An MMIC is mounted by the flip chip method over the second air layer. A coplanar waveguide is on the silicon substrate for connecting the filter and MMIC. The filter having low loss is achieved because it has the microstrip structure using air as an insulating layer. Also change in characteristics of the MMIC during mounting is eliminated because the MMIC is protected by contacting air. Accordingly, the millimeter wave module has excellent characteristics and is made using a simple method.
