Claims (6)
- 軟磁性金属の粉末がシート状のポリマー・マトリクス中に分散したシート(1)の表面に、導体のストリップからなり、直列方向に走る入力信号ライン(2)および出力信号ライン(3)を、間隙を置いて配置し、入力信号ライン(2)および出力信号ライン(3)の上に、両方にまたがって重なり合うように、絶縁体のフィルム(5)を介して、いまひとつの導体のストリップからなる中間ライン(6)を設け、上記シート(1)の裏面にGNDライン(4)を設けた構成を有するGHz帯用バンドパスフィルタを製造する方法であって、絶縁体のフィルム(5)の両面に入力信号ライン(2)、出力信号ライン(3)および中間ライン(6)を設けたものを成型金型キャビティの一方の面にインサートし、他方の面にGNDライン(4)となる金属片をインサートし、軟磁性金属の粉末を分散させたポリマーを成型金型内に射出成形して一体となった成型品を得ることからなるGHz帯用バンドパスフィルタの製造方法。
- 絶縁体のフィルム(5)の両面に入力信号ライン(2)、出力信号ライン(3)および中間ライン(6)を設けたものを、ポリイミド樹脂のフィルムの両面に銅箔を接着したものをエッチングすることによって製造する請求項1の製造方法。
- GNDライン(4)となる金属片として、リン青銅の板を使用する請求項1の製造方法。
- 軟磁性金属の粉末を分散させたポリマーが、軟磁性金属の粉末を、無機質物の粉末とともにポリフェニレンサルファイド樹脂に分散させたものである請求項1の製造方法。
- 軟磁性金属の粉末として、Fe−13Cr合金、パーマロイ、センダストおよびフェライトから選択したものの粉末を使用し、無機質物の粉末として炭酸カルシウムの粉末を使用した請求項1の製造方法。
- 軟磁性金属の粉末を分散させたポリマーの成型金型内への射出成形を、GNDライン(4)となる金属片に設けた射出成形用の孔(41)を通じて行ない、この金属片に設けた別の逆テーパを有する孔(42)の中にポリマーを進入させることによって、得られる成型品の一体化を確保する請求項1の製造方法。
