PURPOSE:To obtain an inductance circuit to be operated in a microwave band with a little parasitic capacity. CONSTITUTION:This Microwave Integrated Circuit(MIC) is equipped with an MIC substrate 1 with a line pattern 2 existent at the inductance circuit formed on this MIC substrate 1 and a cavity part 4 on the plane of connection with a metal base 3 to which this MIC substrate 1 is connected. Thus, capacity between the line pattern of the inductance circuit and the metal base can be reduced rather than conventional capacity, and an operating frequency as an inductor can be more increased. |
