Low-Noise Voltage Controlled Oscillator with Coupled Microstrip Lines of Different Lengths
Известия высших учебных заведений России: Радиоэлектроника, 2020 Introduction. Coupled two- or three-wire microstrip lines are often used to reduce a phase noise of voltage-controlled oscillators (VCOs). Unfortunately, the phase noise was not optimized depending on the lengths of a three-wire coupled microstrip lines ...
