Abstract : Theory and measurement techniques for obtaining the dielectric constant and loss tangent for ferroelectric materials at microwave frequencies, and the experimental results using these techniques are included. Results of investigations of methods for processing ceramic (polycrystalline) materials for use at microwave frequencies are reported. Methods of investigating the nonlinear properties of ferroelectric materials biased in the paraelectric region are described, and results obtained using these methods are included. General application of ferroelectric materials for microwave components is discussed; results of the design and evaluation of a 1 GHz passive power limiter are reported. (Author)
