Abstract

PURPOSE:To minimize the size of a choke which crosses vertically to the tube axis, by using a stub angle also as an impedance converter. CONSTITUTION:A stub angle 11 is also used as an impedance converter that ensures the matching with a coaxial line 8. With such rotary joint, Z4=(Z1.Z2)<1/2> is satisfied, where Z4, Z1 and Z2 are characteristic impedance of the angle 11, a terminal 5 and a coaxial line 6 respectively. Then the equivalent line from the side of the line 6 to the line 8 is set identical with 1/4 wavelength. As a result, the angle 11 can have an operation equivalent to an impedance converter. Thus the distance l2 can be greatly reduced between the tube axial center of a choke 3 and the terminal 5 for the rotary joint of such constitution.
