INTRODUCTION
ThankyouforpurchasingtheAR2300.
AR2300isahigh-endblack-boxtypereceiverwithwidebandcoveragebetween40kHzand3.15GHz.Someofits
outstandingfeaturesare:
1)Digitalsignalprocessing:
Inputsignalsafterthe45.05MHzIFareconvertedfromanalogtodigitalbyaDSPprocessor.ThereisnoAGCin
theanalogprocessingunit,asallprocessing,includingAGC,isdonebyDSP.
2)High-performanceanalogfront-end:
Analogsignalprocessingisperformedbyacomputersimulated,high-performancedistributionconstantfilter.
3)DDSlocaloscillator:
InsteadoftheconventionalPLLmethod,thefirstlocalfrequencyisproducedbydirectdigitalsynthesis.That
methodallowsfrequencyswitchingathighspeed.
4)IFoutput:
AnanalogIFof15MHz(+/-7.5MHz)bandwidthisoutput.
5)DigitalI/Qoutput:
