4.1 Analog frequency dividers and their performance

• Use and main types of analog frequency dividers

  Most microwave systems feature a microwave source frequency-stabilized by a phase-locked loop. Frequency dividers are an important component of these subassemblies. Starting from a microwave frequency, these loops include a frequency division to perform a phase comparison with the signal emanating from a reference oscillator such as a quartz oscillator. This division can be up to a factor of 100, but much of it can be performed by digital dividers. These dividers operate at frequencies of around ten or several tens of GHz in Si technology
