UNIT- IV TRANSFER ELECTRON DEVICES INTRODUCTION: The application of two-terminal semiconductor devices at microwave frequencies has been increased usage during the past decades. The CW, average, and peak power outputs of these devices at higher microwave frequencies are much larger than those obtainable with the best power transistor. The common characteristic of all active twoterminal solid-state devices is their negative resistance. The real part of their impedance is negative over a ra...
