    Abstract: A highly compact bandpass filter that has excellent mechanical strength is disclosed. A bandpass filter according to the present invention employs a dielectric block of substantially rectangular prismatic shape constituted of a first portion lying between a first cross-section of the dielectric block and a second cross-section of the dielectric block substantially parallel to the first cross-section and second and third portions divided by the first portion and metal plates formed on surfaces of the dielectric block. The first portion of the dielectric block and the metal plates formed thereon are enabled to act as an evanescent waveguide. The second portion of the dielectric block and the metal plates formed thereon are enabled to act as a first resonator. The third portion of the dielectric block and the metal plates formed thereon are enabled to act as a second resonator. The metal plates include an inductive stub formed on the surface of the first portion of the dielectric block.

    Abstract: A highly compact and easily fabricated band pass filter is disclosed. A band pass filter according to the present invention employs a first half-wave (&lgr;/2) resonator having a first open end on which an input terminal is formed and a second open end opposite to the first open end, a second half-wave (&lgr;/2) resonator having a third open end on which an output terminal is formed and a fourth open end opposite to the third open end, and an evanescent waveguide interposed between the second open end of the first resonator and the fourth open end of the second resonator. The first half-wave (&lgr;/2) resonator, the second half-wave (&lgr;/2) resonator, and the evanescent waveguide being single-unit. An air gap does not have to be formed by mounting components on a printed circuit board. Therefore, the overall size of the band pass filter can be miniaturized and fabrication of the band pass filter is simplified.

    Abstract: A high power tunable filter, for use in a frequency hopping system, is described and includes a transmission line having an input for receiving a high power level input signal to be filtered, and an output. The filter includes a plurality of resonators, each parallel-coupled to the transmission line, and driven by an associated electronic tuning network. Each of the electronic tuning networks includes a plurality of tunable reactive elements and PIN diodes, each PIN diode connected to one of the tunable reactive elements to enable this diode to connect its associated tunable reactive element in and out of the tuning network, thereby controlling the resonant frequency of the resonator associated with the tuning network. An electronic control circuit is also provided for controlling the frequency of the tunable filter. The electronic control circuit includes appropriate input circuitry for entering a desired frequency of the tunable filter, and an addressable look-up table responsive to the input circuitry for converting the desired frequency into a unique binary codeword. Switch drive circuits are also provided, responsive to the bits of the binary codeword, for controlling the operational states of the PIN diodes.
