A kind of PbTiO3 piezoelectrie ceramies modified with (Pb1/2 Ni1/2)MnO3 is recommended. It possesses fine VHF performances. Its coupling factor Kt is 0.48; mechanical quality factor QM is high; and frequeney stability is good.With the above mentioned material, We have assembled a 62 MHz band-pass filter which consists of seven vibrators. Its stop-band attenuation reaches 30 dB; insertion loss is 6 dB; the ripple ratio of pass band is 0.5 dB; while the rectangular ratio is 3.4.The depolarization phenomenon appearing in this kind of PbTiO3 ceramics is discussed. It is proposed howto overcome the depolarization phenomenon. And it is thought that this kind of ceramics may be an ideal material for developing PbTiO3 surface wave devices.
