Abstract
A high-frequency circuit apparatus includes two high-frequency circuits (2, 3) mounted on a printed circuit board (1), two rows of first plated through holes (6) which connect upper and lower ground plates (4, 5) on the upper and lower surfaces of the printed circuit board (1) and which are arrayed in a first direction so that the two high-frequency circuits (2, 3) are disposed between the first plated through holes, and at least two columns of second plated through holes (7) which are arrayed in a second direction different from the first direction, between the two high-frequency circuits to connect the ground plates on the upper and lower surfaces of the printed circuit board, to thereby form a waveguide resonator. A variable capacitance diode can be provided to be connected to a conductor pattern which is electrically isolated from the ground plates and the ground plates so as to adjust the resonance frequency of the waveguide resonator.
