Selection and Application of LDO in Frequency Synthesizer for Certain Radar
Wang Xiao-Lin · Journal of Sichuan Ordnance · 2011
Aimed at that they are very sensitive to the phaselocked loop circuit,RF transceiver and DAC for power noise of frequency synthesizer of certain radar,and if the power was supplied by switch power,then it will result in fall of circuit performance substantially,and therefore LDO was adopted to improve the above circuits.In the paper,it took the frequency synthesizer of certain radar as an example,explored the related design of LDO to realize the rejection ratio of high power and the low noise in large band width rage.
