<p>PROBLEM TO BE SOLVED: To provide a Gunn diode for preventing the dispersion of characteristics or the generation of any unnecessary signal components. SOLUTION: A signal electrode 15 is formed on the surface of a semi- insulating plane substrate 31, and a ground electrode is formed on the back face in a micro strip line, and a surface ground electrode 16 connected from the ground electrode on the back face through a via hole is formed on the surface of the microstrip line, and the first and second electrodes of a Gunn diode 13 are respectively connected with the signal electrode 15 and the surface ground electrode 16, and a filter element 36 for cutting oscillation frequencies is constituted on the microstrip line 14 on the surface of the plane substrate 31.</p> |
