Noise filter of high frequency generator |
摘要 |
A noise filter of a high frequency generator reduces noise of a certain frequency band leaked from the high frequency generator using a structure in which a first core inductor, an air-core inductor and a second core inductor are connected in series to each other. The first and second core inductors have high frequency-energy absorbing members inserted thereinto, and the air-core inductor is not provided with a high frequency-energy absorbing member therein. The high frequency-energy absorbing member is made of one of iron oxide, tin alloy and ferrite. The high frequency-energy absorbing member is also provided with a sectional area in which noise of a frequency band of 400 MHz to 900 MHz is attenuated.
