Abstract:

A study was made of jump phenomena in harmonic generators and parametric amplifiers, employing varactor diodes. Jump phenomena occurring in circuits employing varactor diodes are attributed to the effect of the capacitive nonlinearity of the diodes when they are pumped via a narrowband impedance transforming network. Experiments demonstrating the qualitative correctness of the above statement are described. Observed astable and bistable behavior of varactor diode circuits, hertofore not explained, are attributed to the occurrence of an rf-induced negative resistance when the circuit is operated near the region where the pump circuit is unstable due to the capacitive nonlinearity of the diode. Some possible applications of the rf-induced negative resistance are mentioned. Author
