Abstract: A printed film RF micros trip bandpass filter includes a plurality of resonators disposed on a dielectric substrate, first and second input/output (I/O) interfaces connected to corresponding first and second resonators flanking one or more intermediate resonators. Opposite ends of the one or more intermediate resonators are connected to a ground plane on an opposite side of the substrate by corresponding conductors. The intermediate resonators have an electrical wavelength that is one-half a wavelength of a center frequency of the filter and the first and second resonators can have an electrical wavelength that is nominally one-half the wavelength of the bandpass filter center frequency.

Abstract: A hybrid-harmonic waveguide filter includes transformer sections at end terminals of the harmonic waveguide filter, a number of corrugations along the length of the waveguide filter, and multiple ridge interconnects that couple the corrugations. By shaping the identical-cross-section ridge interconnects via single-pass wire electrical-discharge machining (EDM), low manufacturing cost is achieved along with continuous broadband rejection of TEn0 modes and an extremely high-power handling capability is observed.

Abstract: The transmission line is provided with a signal strip, a resistive layer opposed to the signal strip across a dielectric layer, and a ground conductor electrically connected to the resistive layer, wherein, in the case where resistance per unit length occurring when a high frequency current induced in the resistive layer through capacitance formed by the dielectric layer between the signal strip and the resistive layer flows in the resistive layer and between the resistive layer and the ground conductor at the time of transmission of a high frequency signal of a predetermine frequency through the signal strip is defined as additional resistance and resistance per unit length occurring when the high frequency current flows through the ground conductor is defined as ground resistance, the additional resistance is larger than the ground resistance.
