Abstract

PURPOSE:To improve the workability considerably and to improve the high frequency characteristic, by forming the active metal film of such as titanium on the surface of a helix then jointing it with a heat-resistant dielectric material rod such as bellyria. CONSTITUTION:A titanium coating 15 having the width of approximately 1/2 of the tape width of the helix and the thickness of several mum is formed through the masking on the surface of the helix 14 formed with a molybdenum tape in a helix delay wave circuit 21 where the helix 14 is secured by three dielectric material rods to the inside of a tubular metal casing 12. After assembling a bellyria dielectric rod 13, it is heated in the vacuum of 1X10<-4>-1X10<-6> Torr under the temperature of 900-1,000 deg.C to perform the titanium brazing. Since only the active metal film on the surface of the helix 14 is brazed, the work can be simplified considerably while the defective brazing is eliminated resulting in the considerable improvement of the characteristic.
