摘　　要：基于某测试系统宽带本振的指标要求,设计了一种双端加载可变电容的宽带压控振荡器(VCO),采取负阻分析法对电路结构进行分析设计,采用ADS对电路进行仿真设计,并通过实物验证设计结果的真实性和有效性。设计指标:频率为2.00～3.30GHz,相位噪声指标小于-80dBc/Hz@10kHz,输出功率大于5dBm。A design of wideband voltage controlled oscillator （VCO） with dual-load varactors microstrip resonator is presented for instrumentation. The method of negative resistance is used in designing. By the simulation of ADS, the VCO circuit is working in bandwidth of 2.00-3.30 GHz; its phase noise is better than -80 dBc/Hz@10 kHz, the output power is more than 5 dBm. The authenticity and effectiveness of the design is proved by the physical circuit.
