| description | To provide a millimeter-wave radar device in which the oscillation frequency of a DC/DC converter can be set to a desired frequency, so that the design freedom of the DC/DC converter is improved.SOLUTION: In a millimeter-wave radar device, a common mode choke coil 5 is provided between a DC/DC converter 3 and a radar unit 2. The common mode choke coil 5 includes a first coil 5a connected to a ground line and a second coil 5b connected to a power supply line. The ground line connects between first ground G1 which is a reference potential of the DC/DC converter 3, and second ground G2 which is a reference potential of the radar unit 2 and is electrically separated from the first ground G1. The power supply line connects between a voltage output end of the DC/DC converter 3 and the voltage input end of the radar unit 2. A pair of capacitors 6a and 6b with the same capacitance value are connected in parallel to the first coil 5a and the second coil 5b, respectively.SELECTED DRAWING: Figure 1
【課題】 ＤＣ／ＤＣコンバータの発振周波数を所望の周波数に設定できて、ＤＣ／ＤＣコンバータの設計の自由度が向上するミリ波レーダ装置を提供する。【解決手段】 ＤＣ／ＤＣコンバータ３とレーダユニット２との間には、コモンモードチョークコイル５が設けられる。コモンモードチョークコイル５は、グランドラインに接続される第１コイル５ａと、電源ラインに接続される第２コイル５ｂを有する。グランドラインは、ＤＣ／ＤＣコンバータ３の基準電位となる第１グランドＧ１と、レーダユニット２の基準電位となり、第１グランドＧ１と電気的に分離される第２グランドＧ２との間を結ぶ。電源ラインは、ＤＣ／ＤＣコンバータ３の電圧出力端とレーダユニット２の電圧入力端との間を結ぶ。第１コイル５ａおよび第２コイル５ｂには、それぞれ並列に同じ容量値を持つ一対のコンデンサ６ａおよび６ｂが接続される。【選択図】 図１ |
