Abstract : The feasibility of a simple add-on noise blanker for use in the HF range is investigated. Various types of noise blankers are reviewed and the advantages of operating at RF as opposed to IF are established. Performance of gate circuits of varying complexity using PN junction and Hot Carrier diodes is evaluated. To demonstrate the potential of this type of blanker, a simple experimental model is constructed and tested. An improvement in S/N ratio of up to 60 db is obtained for weak signals masked by impulse noise. (Author)
