Abstract

PURPOSE:To obtain a local oscillator for the multiple radio unit featuring the fail-safe function by realizing the sharing of the unit design and the stock production as well as improving the FM noise. CONSTITUTION:The n-multiplication is given to the output of crystal oscillator 5 via multiplier 4, and then the injection synchronization is applied to high-stability cavity resonator 2 from circulator 3 in order to stabilize the frequency.
