Frequency modulation of Gunn oscillator by low magnetic flux
Abstract
The oscillation frequency modulation due to low magnetic flux density applied to a Gunn oscillator MA86501 under rated bias voltage deep beyond the threshold is investigated. Concepts of the simplified magnetodynamic effect, successive collision effect, and successive collisions with a variable number of collisions are employed to theoretically explain this phenomenon. It is determined that the oscillation frequency decrease due to transversely applied dc magnetic flux density in the range of 0-0.125 T on the F Gunn oscillator is mainly based on the classical magnetodynamic effect. However, the multiple collision concepts are also found to be useful for explaining this phenomenon.
