The current status and the principal problems of developing microwave transistors /Review/

The state-of-the-art of microwave transistors is reviewed with reference to published theoretical and experimental work in this field. In particular, attention is given to the development of bipolar and field transistors, hybrid integrated circuits, and monolithic integrated circuits including low-noise input devices, high-power circuits, digital logic circuits, and GaAs circuits combining digital and analytic signal processing. Finally, future prospects for the development of microwave integrated circuits are discussed.
