Abstract : The use of a dissipative dielectric material to effectively suppress the spurious responses of low-pass and band-pass filters is described. Data describing the frequency behavior of the attenuation constant, permeability, and permittivity of a number of dielectric materials are presented. Filter design procedures including construction of impedance matching tapers are discussed. Several examples of the use of dissipative filter techniques are given. The use of dielectric materials to reduce the size of resonators in the HF region is considered. Some measurements of the relative shielding effectiveness of lossy dielectric materials are presented. A technique of rapid insertion loss measurement is outlined.
