Phase-Adjusted Microwave Oscillators Based on a Discriminator

by Vladimir Mushegovich Gevorkyan, Yuri Alekseevich Kazantsev and Sergey Nikolaevich Mikhalin

Advances in Science, Technology and Engineering Systems Journal, Volume 6, Issue 3, Page # 319–325, 2021; DOI: 10.25046/aj060336

Abstract:

At the conference “System timing, shaping and signal processing” “SYNCHRONO-2020” there was report: “Simulation of steady state microwave oscillator with dielectric resonator” and “Microwave generators, driven by voltage-based microassemblies with dielectric resonators”. An algorithm for calculating a generator with an open dielectric resonator is described. Based on the DesignLab 8.0 simulation environment, the analysis of…

5G mm-wave Band pHEMT VCO with Ultralow PN

by Abdelhafid Es-Saqy, Maryam Abata, Mohammed Fattah, Said Mazer, Mahmoud Mehdi, Moulhime El Bekkali and Catherine Algani

Advances in Science, Technology and Engineering Systems Journal, Volume 5, Issue 3, Page # 487–492, 2020; DOI: 10.25046/aj050360

Abstract:

Oscillator phase noise (PN) has a strong impact on the spectral purity of the RF signal in wireless systems and is, therefore, a main challenge when designing a local oscillator. In this paper, we propose a new approach for designing a low PN oscillator based on the Time-Invariant Linear Model of phase noise. It leads…
