Description
technical field [0001] The invention belongs to the field of electronic devices and relates to a frequency synthesizer, in particular to a planar integrated YIG frequency synthesizer structure. Background technique [0002] VCO (Voltage Controlled Oscillator) and YIG (Yttrium Iron Garnet) oscillator are the key components to realize the miniaturization design of microwave frequency synthesizer, and YIG oscillator has excellent low phase noise characteristics and good ultra-wideband linear continuous The tuning feature makes it an irreplaceable position in modern electronic equipment and systems. The YIG frequency synthesizer implemented by discrete components and coaxial connection is the main implementation at present. Different from the VCO voltage tuning method, the YIG oscillator is a current tuning device, and its main line package and FM line package respectively realize the coarse preset and fine tuning of the output frequency of the YIG oscillator. The low-pass fil...
