我校微电子研究室多年来从事结型场效应管的研制工作,以期为国内精密电子仪器提供高输入电阻、低噪声和优质温度性能对称管系列。现产品已在国内十六个省,市六十多个科研,生产单位正常使用,普遍反映性能良好,获得信誉。主要产品有:超高输入电阻对称管3DJ15、优质通用型对称管3D Microelectronics Laboratory of our school for many years engaged in the development of junction FET, with a view to the domestic precision electronic equipment to provide high input resistance, low noise and high temperature performance of the symmetrical tube series. Products are now in the domestic 16 provinces and cities more than 60 scientific research and production units in normal use, generally reflect the good performance, access to credibility. The main products are: high input resistance symmetry tube 3DJ15, high-quality general-purpose symmetry tube 3D
