一、引言 双极线性电路在100MHz以上是难于集成的。随着集成工艺技术的发展,国外出现了几百兆的双极线性单片集成电路。这种高频单片集成电路,除具有一般集成电路的优点外,还使整机的安装调试和批量生产更为方便。所以,国外几百兆的高频电路越来越多地采用单片集成的形式。但这方面的报导很少,且无详细介绍,我 I. INTRODUCTION Bipolar linear circuits are difficult to integrate above 100MHz. With the development of integrated process technology, hundreds of trillion bipolar linear monolithic integrated circuits have appeared abroad. This high-frequency monolithic integrated circuit, in addition to the advantages of a general integrated circuit, but also make the whole installation and commissioning of mass production more convenient. Therefore, hundreds of megabytes of high frequency circuits abroad are increasingly adopting the form of monolithic integration. However, there are few reports in this area and no details about me
