LO Board for 704.42 MHz Cavity Simulator for ESS

Igor Rutkowski , Krzysztof Marek Czuba , Maciej Grzegrzółka


This paper describes the requirements, architecture, and measurements results of the Local Oscillator (LO) generation board prototype. The design will provide low phase noise clock and heterodyne signals for the 704.42 MHz Cavity Simulator for the European Spallation Source. RF signal detection has critical influence on the simulation’s performance and its quality depends on the quality of the two aforementioned signals. The clock frequency is a subharmonic of the reference frequency and choice of the frequency divider generating the clock signals is discussed. The performance of selected dividers was compared. The LO frequency must be synthesized and frequency synthesis schemes are investigated. Critical components used in the direct analog scheme are identified and their selection criteria were given.
