TLDR
In this paper, a simple theory of a possible f.m. noise source peculiar to Gunn-effect oscillators is presented and compared with experimental data, showing that the spectrum of cavity-controlled oscillators has an F1 noise power considerably greater than the a.m noise power.Abstract:

Characteristics and applications of a Schottky-barrier-gate Gunn-effect digital-device
TL;DR: In this article, the authors developed a theory for the characteristics of a Schottky-barrier-gate Gunn-effect digital-device (SBG GEDD) for GaAs and derived the device characteristics such as output current, maximum trigger sensitivity, trigger capability, amplification factor, fan-out, noise margin, jitter, unidirectionality, and power-delay product.

Noise generation under large signal conditions in the Read microwave avalanche diode
TL;DR: In this paper, the noise generation mechanism of the Read microwave avalanche diode is examined using a large signal approximation to the operation of the device as an oscillator, the current variation with time in the avalanche region is examined and an expression for the variance of this current, due to fluctuations in the ionization process, is obtained.

Kenji Kumabe,Hiroshi Kanbe +1 more
TL;DR: In this paper, theoretical analysis and experimental results on a GaAs travelling-wave amplifier are presented. But the experimental results are confirmed to be in good agreement with the theoretical predictions analyzed by an equivalent circuit including the effect of coupling between microwaves and space-charge waves at the input and output and the impact of the feedback loop.
