PROBLEM TO BE SOLVED: To provide a frequency circuit device that has improved mass productivity, and has improved high-frequency characteristics of a circuit including such heat generation elements for power, and a radar having the high-frequency circuit device. SOLUTION: A substrate material having high thermal conductivity is used as the substrate material of a substrate region 1, having high thermal conductivity, that is a first region, a substrate material for constituting a line with a high Q is used as the substrate material of a substrate region 2 having a high Q that is a second region 2, a substrate that is made of the two kinds of substrate materials is brazed to a grounding heat radiation conductor plate 3, a gun diode 5 that is a heat generation element is packaged at the first region, and an open stub resonator 41 and an output line 42 are formed at the second region. |
