变频器件是超外差接收技术中的核心部件之一。微波领域中除晶体变频外由于缺乏合宜的微波变频器件致使微波接收设备至今不能充分发挥超外差接收技术。本文研究变频行波管的最终目的即在解决这个问题。这个管种也是目前国外大力开展研制的新管种。文中扼要的比较了现有各种微波变频管的优劣。指出微波接收管也正经历着和低频无线电时相同的过程,从简单管到复合管。文中报导了我们对3厘米变频行波管的研究工作,从设计到制造,并进行了大量测试,获得了良好的结果,最近已装成整机试用。从我们已获得的实验结果,充分证明行波管变频不仅可能,而且变频性能优良,胜过晶体很多,因而预期微波变频工作的前途很大。
Frequency conversion device is one of the core components in superheterodyne receiving technology. Microwave field in addition to crystal frequency conversion due to the lack of appropriate microwave frequency conversion device so that the microwave receiver device so far can not give full play to super-heterodyne reception technology. In this paper, the ultimate goal of frequency-conversion traveling wave tube is to solve this problem. This species is also currently vigorously developed a new type of foreign pipe. The article briefly compares the pros and cons of various existing microwave frequency conversion tube. Pointing out that microwave receivers are also going through the same process as low frequency radios, from simple tubes to composite tubes. The paper reports on our research work on the 3 cm variable frequency traveling wave tube, from design to manufacture, and conducted a large number of tests, obtained good results, recently installed into the machine trial. From the experimental results we have obtained, it is fully proved that traveling-wave tube frequency conversion is not only possible, but also excellent in frequency conversion performance, which is better than that in many crystals. Therefore, the future of microwave frequency conversion work is expected to be very promising.
