Abstract
A transceiver device includes a dielectric substrate, a ring member that is welded onto the dielectric substrate thereby forming a plurality of cavities, a cover that is welded onto the ring member, and at least one semiconductor device that is arranged in each of the cavities. The ring member has at least one passage that communicates between adjacent cavities. The passage is provided at a position shifted by substantially λg/4 or substantially n×λg/2+λg/4 from a center axis of the cavities. If there are two or more passages, the passages are arranged at a λg/2 interval, and one of the passages closest to the center axis is at a position shifted by substantially λg/4 from the center axis.
