Transferred Electron Amplifiers and Oscillators

IEEE Transactions on Microwave Theory and Techniques, 1970
The current status of transferred electron devices (TEDs) is surveyed. The physics of the transferred electron effect, the theory of amplifiers and oscillators, material growth, device fabrication, and the design of amplifier and oscillator circuits are discussed along with a presentation of the outlook for the near future.

AMPLIFIERS IN MEDICAL ELECTRONICS

Acta Anaesthesiologica Scandinavica, 1962
SUMMARYA brief description of the operation of thermionic valves is given. This leads to the design of multi‐stage amplifiers. Methods are presented for coupling stages of amplifiers required to handle signals of an alternating or direct nature. Some idea is given of the mode of action of transistors, and a comparison drawn between valve and transistor

Stabilized Supercritical Transferred Electron Amplifiers

IEEE Journal of Solid-State Circuits, 1969
GaAs transferred electron devices having nl products as large as 4 X 10/sub 12/ cm/sup -2/ have been stabilized by circuit loading to obtain linear reflection-type amplification. Peak output power in excess of 1 watt has been obtained at C band.

Ultra small electron beam amplifiers

1986 International Electron Devices Meeting, 1986
While the tube industry has achieved an extraordinary record of success in increasing the power available at a given frequency by about 10 dB per decade, little attention has been devoted to devices with power outputs on the order of one Watt for which there is likely to be an increasing demand for NASA, commercial and military applications as small ...

35-GHz transferred electron amplifiers

Proceedings of the IEEE, 1973
GaAs transferred electron amplifiers with 110-mW saturated power output at 35 GHz have been designed and fabricated. Small signal gain of 13 dB, 3-GHz bandwidth, and noise figures as low as 16.2 dB have been observed. Two basic amplifier designs which have been investigated are described.

Electron tube Amplifiers

Measurement Techniques, 1966
Up-to-date electrometer tube amplifiers are a perfect equipment for measuring currents and voltages from sources with a large internal resistance, and they can be used for solving a wide range of problems related to electrometric measurements. The current sensitivity of mass-produced tube electrometers amounts to 10−15−10−14 A.
