FIELD: radio engineering, communication.
SUBSTANCE: ceramic filter consists of two partially metal-coated units in the form of a rectangular parallelepiped made of high-Q thermally stable ceramic connected by faces with identical metal coating in form of an E-plane diaphragm, which forms in the connected filter units a chain of directly coupled resonators. Input and output communication elements are made on the end faces of the units.
EFFECT: improved manufacturability and mechanical strength of microwave filters, enabling assembly on microstrip and coplanar lines.
