摘要 变容二极管调谐压控振荡器的非线性压控特性一般都比较严重,尤其是在宽频带进行调谐时更是如此。在锁相频率合成器中,由于压控灵敏度的变化,环路增益也将产生同样大小的变化,这就妨碍了环路特性的最佳化。为了改善压控振荡器的压控特性,在控制电路中插入线性化网络。本文介绍压控振荡器线性化网络的方案和工程设计。 The varactor-tuned voltage control oscillator generally has a quite nonlinear tuning char- acteristic, especially when tuned over a wide frequency range. In frequency synthesis by phase lock, the loop gain will vary by the same amount due to this effect, which generally im- pedes optimization of loop performance. To improve VCO voltage control characteristic, lin- earization network are inserted in control circuit. This paper describes schemes and engineer- ing design for VCO linearzation network.
