Reactance circuit module

Abstract

Abstract PURPOSE:To improve the resistance to electromagnetic interference by constituting a reactance module with a coaxial line having an inner conductor whose both ends have the same diameter and whose center is regularly conical so as to attain no-distortion transmission. CONSTITUTION:The inner conductor of the coaxial line is formed to have the same diameter at both ends 4 and to be a regular conical shape at the center 3. Through the constitution above, the junction capacitance at both ends is made smaller in comparison with that of a conventional line to improve the distortion in the transmission characteristic. Further, since the module is shielded by an outer conductor 1, the resistance to electromagnetic interference is also improved. Since the reactance module module of this constitution is constituted by the inner conductor of regular conical shape, the characteristic impedance is designed equivalently to be 50OMEGA easily and the module is used as a low-pass filter by connecting it in multi-stage cascade.
