摘要：
A high-frequency filter 10 serving as a bandpass filter has three transmission lines SL11 to SL13 side-coupled in three stages. The transmission lines SL11 to SL13 are respectively connected in parallel to capacitors C11 to C13. One end of the input transmission line SL11 is connected to an input terminal Pi through an input capacitor C14. One end of the output transmission line SL13 is connected to an output terminal Po through an output capacitor C15. The other ends of the transmission lines SL11 and SL13 are connected and the connection point is connected to the ground through an inductor Lg for forming a pole. One end of the transmission line SL12 is connected to the ground.
