Lecture: Low Phase Noise Signal Generation
September 14 @ 18:00 - 21:00FREE
Low Phase Noise Signal Generation utilizing Oscillators, Resonators & Filters and Atomic Clocks
Distinguished Microwave Lecturer – Dr. Jeremy Everard, Professor of ElectronicsDepartment of Electronic Engineering, University of York Heslington, York,
This talk will discuss the theory and design of a wide variety of oscillators offering the very best performance. Typically, this is achieved by splitting the oscillator design into its component parts and developing new amplifiers, resonators and phase shifters which offer high Q, high power handling and low thermal and transposed flicker noise.
Key features of oscillators offering the lowest phase noise available will be shown, for example: a 1.25GHz DRO produces -173dBc/Hz at 10kHz offset and a noise floor of -186dB and a 10 MHz crystal oscillator shows -123dBc/Hz at 1Hz and -149 at 10Hz.
New compact atomic clocks with ultra-low phase noise microwave synthesiser chains (with micro Hz resolution) will also be briefly described to demonstrate how the long-term stability can be improved.
