Frequency divider module for the European XFEL phase reference signal distribution system

This document presents a compact module of an RF frequency divider, working with 1.3 GHz input signal, producing 216 MHz and 10 MHz output signals, designed for use in RF phase reference distribution system in European XFEL facility. Presented module is small, relatively simple in production and easy to use, including simple synchronization with other devices. For the European XFEL more than 70 modules have been manufactured, tested and installed in the accelerator, and their robustness and quality proved. In this article principle of operation, block diagram, module photos and test results are presented.
