Abstract
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.
