Abstract

The invention discloses an imprisoned radio frequency source for a mercury ion microwave frequency marker, in order to solve the problems of low frequency and poor stability of the existing imprisoned radio frequency source for the mercury ion microwave frequency marker. The imprisoned radio frequency source comprises an oscillator, a phase shift splitting module, a first power amplifier module, a second power amplifier module, a booster, a first adjustable capacitor, a second adjustable capacitor and an ion trap; the oscillator is used for producing an oscillating signal; the phase shift splitting module is used for dividing the oscillating signal into two paths of positive phase oscillation and negative phase oscillation with opposite phases and identical frequency; the first power amplifier module amplifies the positive phase oscillation to generate a positive phase oscillation amplification signal; the second power amplifier module amplifies the negative phase oscillation to generate a negative phase oscillation amplification signal; and the booster is connected with the output of the first power amplifier module and the second power amplifier module to boost to generate a positive phase oscillation boosting signal and a negative phase oscillation boosting signal and separately input the positive phase oscillation boosting signal and the negative phase oscillation boosting signal in two electrodes of the ion trap. The scheme provided by the invention has the advantages of high frequency stability, stable output voltage amplitude, integration and miniaturization.

Description

technical field [0001] The present application relates to the field of wireless test and measurement, in particular to a radio frequency source. Background technique [0002] Mercury ion microwave frequency standard is a new type of frequency standard source, which adopts a new working principle different from traditional atomic frequency standards such as hydrogen, rubidium and cesium. It has the inherent characteristics of being basically not disturbed by physical particles and external fields, small motion effects and long coherence time of quantum states. The spectral line width is extremely narrow, and various frequency shifts are small. One of the main reasons is that by applying an electrostatic field, magnetic field or radio frequency field to the ion trap, the working ions are trapped in the center of the ultra-high vacuum ion trap, so that the ions are completely isolated and in a "completely static state" without external interference. Therefore, the performance ...
