Research on Improving the Spur-free Dynamic Range of Receiver

The reconnaissance receiver need high sensitive and high dynamic range at the same time in complex electromagnetic environment.The spurious response could restrict the dynamic range of the reconnaissance receiver.RF analog front-end of the reconnaissance receiver is made up of amplifiers,filters,and frequency mixer etc.,the spurious response of RF analog front-end is one technique-bottleneck to realize a large dynamic range receiver.To improve the spur-free dynamic range of receiver system,full consideration of the character of RF analog front-end is required.And many approaches are used in engineering,including optimizing system design,adopting high performance components,and increasing linearity
