Receiver Protector Theory of Operation
■This article will give the reader a basic understanding of receiver protector technology. It discusses the various available types of receiver protector forms, their strengths and weaknesses, and how best to use them. It should be stated at the outset that choosing the best receiver protector configuration for any given application normally involves analyzing the needs of many conflicting operating requirements. Very often, apparent nuances in performance requirements can have a large effect on the final design approach. For those reasons, it is always advisable for the prospective user to consult with BMD's technical experts as early as possible in the design phase of a new application.
■Receiver protectors are used in radar systems to protect the radar receiver from unwanted and potentially damaging high power signals. These signals may the reflected remnants of its own radar transmitter output or they may enter the system from outside sources. In any case, these signals are usually on the order of kilowatts to megawatts of peak power --far too much for any receiver to survive.
■In some configurations, the receiver protector may be a singular component which is located in the receive channel, just before the receiver. In other configurations, the receiver protector may also do “double duty” and actually perform the function of the radar duplexer as well. For that reason, this article will begin with a discussion of common duplexing techniques.
