Abstract
The GHz radio frequency filters are usually made by
connecting several bulk acoustic wave (BAW) resonators to
a ladder form. The harmonic oscillations became
significant in the BAW resonator when the resonator are
driven with high power. The intermodulation in the BAW
resonators caused by the harmonic oscillations of several
signal frequencies may distort the radio signal in the
filter. In this study the power levels of the second and
the third harmonic oscillations near the resonance
frequencies of BAW resonators have been measured. These
harmonic oscillation results are compared with results at
the intermodulation.
