摘要： A microwave bandstop filter comprises a waveguide segment of cross-section that presents longitudinal variation of sinusoidal type modulated by an amplitude function that is continuous, the period of said longitudinal variation of sinusoidal type being the Bragg period for the fundamental guided mode at a center frequency of the band to be stopped. A filter assembly comprises a microwave lowpass filter presenting a cutoff frequency and at least one interfering passband at frequencies higher than said cutoff frequency, and at least one bandstop filter as defined above, connected to the output of said lowpass filter, in which the amplitude and the period of said longitudinal variation, and also the length over which it extends are such that they stop said interfering passband of said lowpass filter. An output multiplexer for a multichannel microwave transmitter includes such a filter assembly.

摘要： There is disclosed a method for designing an electrical filter comprising the steps of: a) selecting at least one determined function called seed function; b) determining the product of all these seed functions to define a transfer function generating function of the electrical filter; c) translating the electrical filter transfer function into transmission zeroes and poles; d) and synthesizing those electrical filter dimensions that achieve the required zeroes and poles. A particular application is aimed at a Chebycheff filter comprised of serially arranged resonant cavities and couplers, operating in the microwave range.

摘要： A system for synthesizing a microwave filter including a plurality of resonators having no tuning elements, in particular waveguide filters for use in satellite telecommunications networks. Signals representing the coupling coefficients of the coupling elements having a finite thickness and the resonant frequency of the resonators are stored in an electronic memory. A computation unit is controlled by a control unit arranged to determine automatically, in a single run, the widths of the coupling elements and the lengths of the resonators from the signals representing the coupling coefficients.
