The frequency stability can be divided into long-term stability and short-term stability, wherein the long-term stability is related to factors such as environmental temperature, component aging and the like; short term stability is dependent on the phase noise figure of the system. In order to obtain higher stability, the anti-interference capability of the circuit and the phase noise parameter level of the system need to be improved.
Because the highest operating frequency of the active device is limited, the operating frequency of the common field effect tube can only reach about 20GHz, when the required oscillating frequency exceeds the range, the frequency source with the traditional structure can not meet the requirement, and the push-push frequency source provides a possible implementation scheme. In the push-push frequency source scheme, the design of a power divider circuit at the output end is very critical, and the influence on the overall performance of the circuit is large.
