摘　　要：介绍了一种低杂散Ka频段上变频器的设计,对其中的关键电路进行了较为详细的描述,对杂散产生及抑制的关键技术进行了分析。研制的Ka频段上变频器将甚高频(UHF)频段中频信号上变频至Ka频段,1dB压缩点输出功率大于+17dBm,输出中频带宽内增益平坦度小于3dB,杂散抑制优于50dBc。试验测试结果表明,设计为低杂散上变频器提供了一种适宜工程实现的方法。This paper introduces the design of a low spurious Ka-band up-converter, the key circuit is described in detail, the generation and suppression method of low spurious key technologies were analyzed. The developed Ka-band up-converter realizes the up-conversion of Very high frequency （UHF） IF signal to Ka band frequency band. The ldB output power is greater than ＋17dBm, the flatness of gain in IF band is less than 3riB, the spurious suppression is better than 50clBc. The test results show that the design of low spurious up-converter provides a suitable engineering implementation method.
