On one surface of the dielectric substrate 12, there are a first probe portion 13a and a second probe portion capable of converting the fundamental propagation mode electromagnetic field of the waveguide and the propagation mode electromagnetic field of the microstrip. 13
A strip conductor 14 having a predetermined shape having a shape of It is coated with a ground conductor 17 shaped to prevent direct coupling, and the strip conductor 14 provided on one surface of the dielectric substrate 12 and the ground conductor 17 coated on the other surface form a microstripe. A lip 18 is formed.

結合することを防いでいる。 Now, when a microwave signal enters from the input terminal 15, it propagates in the rectangular waveguide 10 in the fundamental waveguide mode, and propagates in the microstrip 18 at the first probe portion 13a formed of the strip conductor 14. converted to mode. On the other hand, regarding the output side circuit, the propagation mode of the microstrip 18 is converted into the fundamental waveguide mode of the rectangular waveguide 10 at the second probe portion 13b formed by the strip conductor 14, and It propagates through the wave tube 10 and reaches the output terminal 16. Here, part A of the rectangular waveguide 10 is a cut-off waveguide because of the ground conductor 17 coated on one surface of the dielectric substrate 12, and the input terminal 15 of the rectangular waveguide 10 is a cut-off waveguide.
This prevents direct coupling between the side and the output terminal 16 side in the waveguide mode.
