    摘要: A thin-film zinc oxide varistor (10) for use in integrated circuits and the like is produced by applying a polyoxyalkylated metal complex, such as a metal alkoxycarboxylate, to a substrate (12, 14, and 16) for the formation of a dried nonohmic layer (18). The method of production includes the steps of providing a substrate and a precursor solution including a polyoxyalkylated zinc complex (P22, P24), coating a portion of the substrate with the precursor solution (P26), drying the coated substrate (P32), and crystallizing the dried thin-film zinc oxide layer (P30). The resultant crystalline zinc oxide varistor layer (18) may be doped with bismuth, yttrium, praseodymium, cobalt, antimony, manganese, silicon, chromium, titanium, potassium, dysprosium, cesium, cerium, and iron to provide a non-ohmic varistor. The varistor layer (10) is annealed at a temperature ranging from about 400 to about 1000.degree. C. to provide a layer having a thickness ranging from about 50 nanometers to about 500 nanometers and an average grain size diameter less than about 200 nanometers.

    摘要: The microprocessor-controlled RF modulator apparatus will provide repeatable, controlled scintillation on a test bench generated low-power RF target waveforms for the purpose of providing a target returns with realistic radar cross section characteristics during testing of the F-16 (or any other) fire control radar. The microprocessor-controlled RF modulator apparatus is utilized in line between an RF target signal generator and the target horn to provide a variety of target situations for testing radar hardware and software.
