September 1952, Radio Engineering Department of Tsinghua University was founded. The precursor was Telecommunications Group of Electrical Engineering Department founded in 1932.Faculties in Universities and Colleges of China was regulated. In 1952,Telecommunications Group of Electrical Engineering Department in Tsinghua and Telecommunications Group of Electrical Engineering Department in Peking University Engineering Institute was constituted then Tsinghua University Radio Engineering Department was build. The chairman was Pro. Zhaoying MENG and the Vice Chairman was Jiong CHANG. The teachers' branch of Party was build in 1953 winter and the secretary was Chuanxin LI.

From 1952,Nanxiang JIANG had been the headmaster of Tsinghua. He paid attention to Radio Engineering Department. He invited the officers of. The policy that should serve for development of electronic industry was confirmed. And industry department would support build and development of Radio Engineering Department.

At the beginning of department founded, there were 15 teachers, 5 workers and 3 grades about one hundred students. The staff had united and done pioneering work. A cours--The Foundation of radio-had been created, and published two teaching materials of soviet, < The Foundation of radio> and . This was the first time that soviet teaching materials of radio engineering had been published in China. Chinese Academy of Science established some parts in 1955. Pro. Zhaoying Meng was engaged a committee member of Technical Science Part.

From 1956 to 1957, some teachers and students in our department took part in the build of first TV station in China. This was the beginning that scientific works of department served for national economy.

In 1958, Chuanxin LI managed work of department then was appointed chairman. The department's name changed for Radio and Electronics Department. The first grade students graduated in the same year, and teaching program had already been executed. Most teachers and students enter factories. They took part in foundation of electron factories and practice of production that was included by first five years plan.

After that, teaching, researching and production had been combined. The department came in a developing time. The communication with industrial circles and other field of science and technology had been close, then had got their supports.

In 1963, Tsinghua and the tenth research part of the fourth machine ministry established Radio and Electronics lab. in Radio and Electronics Department. The tenth part selected research projects and provided spending. Young researchers in it also attended lab. works. In 1960s' early, it came into being some research orientations including digicom, television, microwave technique, device of microwave electron, vacuum technique and semiconductor device. It recruited postgraduate again at that time.

From 1952 to 1965 there were 3089 students and 96 postgraduates had been recruited. There were 1200 students in the department up to 1966.

In the decade from 1956 to 1966, some projects that were banner inland including data of inputting system, 600/1200 baud sending machine, 8 route PCM communication terminal, 3cm cycle magnetic field focus broadband little power travelling wave tube and 10cm solid low noise parameter amplifier had been finished. Firstly we start to make silicon transistor and study integrated circuit in China. After the beginning of "civilization revolution" in 1966, the conditions were very hard. Some teachers give lessons to the students, and some research group also work in lab. or in cooperation lab..
