本文叙述了一种利用FET振荡管和GaAs超突变结变容二极管构成的电压控制振荡器(VCO).通过合理的电抗补偿和阻抗匹配技术的应用,VCO在8GHz得到调谐带宽1200MHz,输出功率大于20mW.
This article describes a voltage controlled oscillator (VCO) using a FET oscillating tube and a GaAs HLC varactor.With reasonable reactance compensation and impedance matching techniques, the VCO achieves a tuned bandwidth of 1200 MHz at 8 GHz with an output power greater than 20mW.
