微波上变频器是雷达、通讯等电子设备不可缺少的部件,其电路种类繁多、较为复杂。工作于厘米波段的上变频器,目前多采用微波集成电路,用氧化铝陶瓷做为电路基片,用半导体二极管或双极晶体管的非线性进行变频,用微带网络进行匹配,用微带滤波器进行滤波,有的还采用平衡型电路,进一步提高隔离度。这些电路结构复杂,研制周期较长,成本较高。有少数文献报道了用双栅场效应管制成的上变频器,但只介绍了性能和电原理图,没有介绍电路细节,效率 Microwave up converter is an indispensable part of radar, communication and other electronic equipment, and its circuit variety and complexity. Upconverter work in the centimeter band, the current use of microwave integrated circuits, with alumina ceramic circuit substrate, with semiconductor diodes or bipolar transistors of the non-linear frequency, microstrip network to match, with microstrip filtering Filtering devices, and some also use a balanced circuit to further improve the isolation. The circuit structure is complex, the development cycle is longer, the cost is higher. A small number of articles have reported on upconverters made with dual-gate FETs, but only introduced performance and electrical schematics without detailed circuit details, efficiency
