Abstract
The impedance value of the semiconductor device usable at very high frequencies is preset during manufacture. The device comprises a Gunn or Zener diode coupled to a coaxial line. The central conductor of the line is constituted by a metal wire mandrel or a metal coating deposited on a glass fibre section. The outer cylinderical conductor is a cylindrical metal coating deposited on a ring of dielectric material, such as glass and which surrounds the diode. Application to microstrip, transmitting antenna and radial cavity circuits.
