Transmission line type components
First Claim
1. A transmission line type component characterized in that a coaxial line is constructed by coaxially arranging a cylindrical external conductor which is formed from a conductive material and has a larger diameter than that of a columnar or cylindrical internal conductor so as to cover, via an insulating member, a surface of the internal conductor which is formed from a conductive material and extends in one axial direction, and the internal conductor is constructed by integrally forming a first portion which is a portion covered with the insulating member, a second portion which extends from the first portion to a side of the external conductor while covering an end portion of the insulating member, and a third portion which extends from the second portion to be close to the side of the external conductor while having the same diameter as that of the external conductor.

Abstract
Transmission line type components (1, 1′), which form coaxial lines having a very low characteristic impedance by coaxially installing a cylindrical outer conductor made of a conducive material being larger in diameter than an inner conductor so as to cover via a high dielectric insulating material the surface of an inner conductor made of a conductive material, are inserted in series between a power supply line (8) and a ground line (9) connected with a dc source on a printed circuit board and an I.SI (6) power supply port, whereby almost the entire high-frequency power supply current generated from the I.SI (6) is reflected off the I.SI (6) power supply port, and part of the high-frequency power supply current intruding into the components (1, 1′) is consumed and does not reach the external power supply line (8).
