本文介绍把高压面结合型场效应晶体管装成真空管形式,直接插入原有设备的真空管管座里以代替原有的真空管,而原电路基本上无需更动。美国已在电话线路中进行了八个月的实际试用。本文概述了场效应管在特性上与真空管的相似之处,并认为在许多方向比真空管更为优越。可以在一个管壳内用一个场效应管,也可以用两个场效应管接成级联电路,再附加RC网络组成混合式集成电路,而在放大器、振荡器、低频和高频电路中直接替换许多种真空管。日本杂志对此也已有报导。看来这对于充分利用原有设备而又发挥晶体管的优越性具有一定的实用意义。这种管子称为“菲特隆”,即Fetron,此字前三个字母为场效应管三个英文字的第一个字母,后面四个字母是常用于真空管名称的字尾,而第三字母正好前后合用。
This article describes the high-voltage surface-mounted field-effect transistor installed as a vacuum tube form, directly into the vacuum tube tube seat of the original equipment to replace the original vacuum tube, and the original circuit basically without change. The United States has conducted an actual trial of eight months on the telephone line. This article outlines the similarities of FETs to vacuum tubes and considers them to be superior to vacuum tubes in many directions. You can use a FET in a tube, you can also use two FETs connected into a cascade circuit, and then add the RC network hybrid integrated circuit, and amplifiers, oscillators, low-frequency and high-frequency circuit directly Replace many types of vacuum tubes. Japanese magazines have also reported on this. It seems that this for the full use of the original equipment and to play the superiority of the transistor has some practical significance. This tube is called “Fetelon”, Fetron, the first three letters of this word are the first letter of the three English words of the FET, the last four letters are the suffixes commonly used for the name of the vacuum tube, and the third The letters are combined before and after.
