Abstract
The purpose of this thesis is to examine the impedance of a tunnel diode as a fu1nction of frequency and bias voltage. In order to do this, the equivalent circuit of a tunnel diode is examined to determine what frequency or voltage dependencies should exist. Several mounts are examined both theoretically and experiment ally to determine the best one for measurement purposes. Several methods of measurement are examined. Using the reflection coefficient technique, the impedances of several circuits are examined at the start of the mount and at the center of the mount. The impedance of the mount or mount and tunnel diode can be used to predict the effects of connecting such circuits to other devices so that useful functions can be performed. The admittance of the mount is examined as a function of frequency. The tunnel diode admittance is found to be not a measurable function of bias voltage. It is shown that a large signal from outside a tunnel diode can influence the fundamental frequency of its oscillations, even though the external signal frequency is nine times the tunnel diode's fundamental frequency. A small signal at nine times the fundamental frequency is found to interact with the diode and parametrically absorb power from the tunnel diode's oscillations.
