A miniature low phase noise synthesizer in V band has been studied in this paper.An agile synthesizer in L band、a sampling phase locked source in Ku band、an up converter module and a frequency multiplier have been developed.An up converter a multiplier's combination has been adopted to get low phase noise and fast switching speed.In this method
DRO PLS has been applied to be a local oscillator to assure low phase noise performance
and the agile synthesizer in L band has been used to assure fast agile speed.The dimension of synthesizer is 100×80×30mm

the phase noise is below -86dBc/Hz(1kHz)
the switching speed is faster than 40 μs and the spurious output is below -60dBc.
