Abstract :
In this paper we have studied the influence of the material constants on the attenuation characteristics of two-pole langasite monolithic filters and on electrical parameters of langasite resonators. This study was demand by the real dispersion of material constant values for langasite crystals grown in various laboratories. The dispersion of the constants is probably done by the in- homogeneity produced during the langasite growth process.
