Problems solved by technology

[0007] However, in a conventional noise attenuation device such as the above noise filter, the noise attenuation frequency band is limited to 400MHz to 1000MHz
Thus, there may be no noise attenuation effect for noise in the frequency band ranging from 30MHz to 400MHz

Embodiment Construction

[0020] The preferred embodiments of the invention will now be described in detail, examples of which are illustrated in the accompanying drawings, wherein like numerals refer to like elements throughout.

[0021] Refer to the attached Figure 2A , 2B, 3 and 4 describe the noise filter of the high frequency generator of the embodiment of the present invention. first, Figure 2A An inductor of a noise suppression filter according to the present invention is shown. Such as Figure 2A As shown, the choke 204 is configured such that a first cored inductor 204a, a second cored inductor 204b, and a third cored inductor 204c are connected in series with each other. Each of the first cored inductor 204a and the third cored inductor 204c has a relatively dense interval. The second cored inductor 204b has a coarser or larger spacing between its turns than the first cored inductor 204a and the third cored inductor 204c. The core 202 is inserted into the first cored inductor 204a, th...

Abstract

A noise filter for a high frequency generator maximizes a frequency band in which noise is attenuated by adjusting a spacing between winding turns of core inductors provided in the noise filter. The noise filter includes a choke coil having a first winding unit having a first spacing between turns thereof, a second winding unit having a second spacing between turns thereof and a third winding unit having a spacing the same as the first spacing between turns thereof. The first, second, and third winding units are connected in series to each other. The noise filter also includes a high-frequency energy absorbing member inserted into the choke coil. The high-frequency energy absorbing member is made of one of iron oxide, tin alloy and ferrite, and includes a sectional area to attenuate noise in a frequency band ranging from 30 MHZ to 1000MHz.

Description

[0001] Cross Reference Related Applications [0002] This application claims priority from Korean Patent Application No. 2003-2910 filed in the Korean Intellectual Property Office on January 16, 2003, the contents of which are hereby incorporated by reference in their entirety. technical field [0003] The present invention generally relates to a high-frequency generator, and in particular to a noise suppression filter of the high-frequency generator. Background technique [0004] High-frequency generators such as magnetrons, klystrons, traveling wave tubes, and semiconductor devices are used in various fields. High-frequency generators mainly employ noise suppression filters in order to prevent unwanted leakage of high-frequency energy. Leakage of high frequency energy causes noise in electronic devices such as radios and televisions. For this reason, it is important to prevent leakage of high-frequency energy from the high-frequency generator. In general, noise suppress...
