Abstract
PURPOSE: To obtain the optional S-shaped characteristics as well as to realize the adjustment-free state by forming the resonance circuit with the elastic surface wave filter.
CONSTITUTION: Elastic surface wave element 5 is connected between AFT-use phase detector 8 and amplitude limit circuit 2 which performs the amplitude limitation with reception of the output from the video intermediate frequency amplifier ciecuit or the like. For element 5, one input electrode 4 plus two output electrodes 6 and 7 are provided on piezoelectric substrate 12, and the output of circuit 2 is introduced to electrode 4. And the frequency phase characteristics of electrodes 6 and 7 are set properly to the signals delivered from electrodes 6 and 7. In such way, the optional S-shaped characteristics can be obtained, at the same time realizing the adjustment-free state.
