Abstract
Disclosed is an active radial-to-coaxial transmission line wherein an annular configured semiconductor device, such as an IMPATT diode, is embedded in a chosen dielectric material which is in turn positioned between two conductive members forming a radial transmission line. Advantageously, the lower conductive member of the transmission line also serves as a heat sink for the diode, and the upper conductive member of the radial transmission line may be formed as a highly conductive coating which makes good ohmic contact to the diode, thereby minimizing power losses at this contact. The radial transmission line transforms the relatively low impedance of the diode to a substantially higher value at the outer periphery thereof where contact to a coaxial transmission line may be achieved with good impedance matching, thereby maximizing power transfer between the radial and coaxial transmission lines.
