第一节引言 1.1.正交场器件的发展正交埸器件的第一个重大进展,是在1938—1945年间,随着磁控管振蔼器的研制而取得的,战后,美国通用电气公司Wilbur和Peters对电压调谐磁控管的研制(1949年)以及随后密执安大学所进行的研究工作,为正交埸器件开辟了一个新的须域,也指出了研制电压调谐振荡器的新趋向。然而,在五十年代里,在彼形电子注行波放大管和高功率速稠放大管方面的 Section I. INTRODUCTION 1.1. The Development of Orthogonal Field Devices The first major advance of the quadrature field devices was achieved with the development of a magneto-optic adapter from 1938 to 1945. After the war, the United States General Electric The development of voltage-tuned magnetrons by companies Wilbur and Peters (1949) and subsequent research at the University of Michigan opened up a new area for orthogonally-connected devices, as well as the development of voltage-tuned oscillators New trend. However, in the 1950's, in the field of electron injection wave amplifier and high power amplifier tube
