Microwave filter providing mode coupling between non-adjacent cavities - saves vol. and wt. with fewer cavities for transfer of modes not corresp. to circuit resonances

摘要

Two cavity resonators (HR1,HR2) are arranged in line between input and output waveguides (H1,H2) to which they are coupled through slots (K1,K3). Another slot (K2) in a screen couples the cavities (HR1,HR2) in which two resonant circuits (R1,R2) contain TE11 modes. The entry and transfer slots (K1,K2) are offset from the axis of the input resonator (HR1) so that the TMO1m mode in the input waveguide (H1), although not representing either of the resonant circuits (R1,R2), is coupled into the output cavity (HR2). USE/ADVANTAGE - In e.g. space flight, mechanically simple arrangement allows large number of couplings of resonant circuits.
