The prezoelectric ceramic specimen compoxed of PbO, ZrO$_{2}$, TiO$_{2}$ were prepared in this Lab, and showed properties of dielectric constant .epsilon.$^{33}$ /.epsilon.$_{0}$ 487 at 1kHz, electromechanical coefficient Kr 0.524. As the characteristics of piezoelectric HF filter used these piezoelectric specimen were the resonant point 6.7 MHz, effective bandwidth 690KHz, it was exellant. Since a LC resonant filter can be replaced bt this piezoelectric HG filter, it will greatly contribute to compose a compact circuit. If the resont point can be controlled, this piezoelectric HF filter practically.
