摘要
在 Ansoft非线性电路设计软件 Serenade支持下 ,通过变容管的选取 ,输出端的优化匹配 ,设计了一中心频率为 18GHz的高线性度的场效应管介质谐振器稳频振荡器。测试结果表明 ,此振荡器具有非常好的线性度和很低的相位噪声 ,可以为微波锁相环路提供高品质的 DRO。
Applying the advanced ANSOFT non-linear circuit design software Serenade, the paper designed a high linearity FET DRO by selecting varactor and optimizing output matching. The DRO operates at the central frequency of 18GHz. Test results indicated that extraordinary linearity and low phase noise were achieved, and the DRO can be used for microwave phase-locked loops.
