Embodiment Construction
[0031] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.
[0032] see figure 1 and figure 2 , the embodiment of the present invention includes:
[0033] An L-band low-phase-noise frequency source mainly includes a reference source module, a clock signal module, a local oscillator signal module, and a control circuit module.
[0034] The reference source module mainly includes a crystal oscillator signal source and a power divider. The 80MHz reference source signal generated by the crystal oscillator signal source is divided into four channels through the power divider, and is respectively output to the clock signal module, the local oscillator signal module, and the control circuit module to generate ...
