Modern EW exciters, receivers, and simulators require fast-hopping frequency generators (usually voltage-controlled oscillators) in order to identify and jam the threat frequencies encountered. Accurate high-speed hopping allows a single signal generator to cope with a greater number of threats nearly simultaneously. The savings both in cost and size/weight on military platforms can be considerable. One way of addressing this requirement is through a technique called transband. The basic concept of transband during development was to address each of the fundamental technical obstacles one at a time. Therefore, the development strategy was to analyze all the implications of the frequency-hopping problem and then to partition it into solvable segments. The ultimate goal is a broadband exciter capable of covering the 2- to 18-GHz band by upconverting a transband unit in the 2- to 18-GHz exciter band with switchable dielectric oscillators; the dielectric oscillator could be phase-locked to a common master crystal oscillator. Using this technique, ambiguities in a DF receiver mode could be avoided.
