摘要

本文讨论了具有线性化宽带调谐特性的微波压控振荡器(VCO)相位噪声测量的主要结果。在实验中，研究了在带宽为6 ~ 12 GHz时，在振荡器的控制输入端连接一个有源二极管变换器的压控振荡器的特性。控制电压变换器是在一个低噪声放大器和五个肖特基二极管hsm -281x上实现的。本文证明了将调谐非线性系数降低2.8倍以上的可能性。在100khz频偏下，VCO的相位噪声不大于- 90…- 92 dBc/Hz。

Phase Noise Measurement of the Microwave VCO with Linearized Wideband Tuning Characteristic

This article discusses the main results of a phase noise measurement of the microwave voltage-controlled oscillator (VCO) with a linearized wideband tuning characteristic. In the experiments the characteristics of VCO, tuned in bandwidth of 6 to 12 GHz, with an active diode converter connected to the control input of the oscillator were investigated. The control voltage converter is implemented on a low-noise amplifier and five Schottky diodes HSMS-281x. The article shows the possibility of reducing the tuning nonlinearity coefficient more than 2.8 times. VCO's measured phase noise is not more than −90 … −92 dBc/Hz at 100 kHz frequency offset.
