Design of C Band Highly Stabilized CRO

This paper introduced the method with using ceramics resonator to improve the oscillator＇s frequency stability, and using the special microwave circuits design software （AWR） to analyze this method; moreover, we made temperature compensated design in voltage branch. Based on the analysis, we fabricated a C band highly stabilized CRO. It reached a satisfied goals： frequency temperature drift less than 50×10^-6/℃, linearity less than 1.1, frequency stability less than ＋15MHz, phase noise less than -108dBc/Hz/10kHz in the temperature range is from -55℃ to ＋ 85℃. Contrast the computer prediction and testing result, we find they are very close to each other. The method using CR in resonant circuit can realize high frequency stability and low phase noise. It will do good to practise.
