ABSTRACT:
A high-frequency integrated circuit which operates in a microwave band or in a millimeter wave band. The high-frequency integrated circuit has devices with a nonradiative dielectric waveguide such as an oscillator, a circulator, etc., and a mount case with a nonradiative dielectric waveguide in which these devices are mounted. Each of the devices with a nonradiative dielectric waveguide has a couple of conductors, a dielectric strip which is disposed between the conductors and propagates a high-frequency electromagnetic wave in a specified mode, a mounting surface which is formed on one of the conductors, and an end surface which is formed on an end of the conductors so as to be vertical to a traveling direction of the electromagnetic wave propagated in the dielectric strip and on which an end of the dielectric strip is exposed. The devices with a nonradiative dielectric waveguide are evaluated separately, and thereafter, the devices are mounted in the mount case individually.
