| Abstract: | In this paper, some characteristics of lithium tantalate crystal and componentsare introduced simply. The design and production of 21.4MHz wide--band filter usingthis material and measurement results are described in detail. Bandwidth of filter is225kHz, rectangular coefficient (BW_(40dB)/BW_(3dB)) of filter is 2.66, out-of-bandattenuation of filter is over 50dB, This material has distingushed superority in makingwide-band filter and voltage control crystal oscillator. |
