Theoretical and Experimental Studies of the Tuning and Modulation Properties of Transferred-Electron Devices.

摘要

The purpose of the study is to investigate the tuning and modulation properties of transferred-electron devices. The device performance under two basic tuning methods was examined:tuning through the bias voltage of the device and tuning through a resonant circuit. The tuning properties were derived from the interaction between the device and the circuit. Thus,both the device and the circuit admittances are needed for the investigation. Two conventional cavity circuits which were employed in these investigations,namely,the post-mount waveguide cavity and the slug-tuned coaxial-line cavity,had already been modeled and well understood. This study,therefore,concentrated on the nonlinear properties of the transferred-electron device. (Author)
