ABSTRACT:
A spectrum analyzer includes an array of frequency-selective bulk acoustic wave (BAW) resonators each tuned to a predetermined different resonant frequency. The spectrum analyzer further includes a broadband BAW resonator that generates acoustic energy when connected to a signal source. An acoustic coupling transmits the acoustic energy generated by the broadband BAW resonator to the frequency-selective BAW resonators so that one of the frequency-selective BAW resonators will generate an electrical output signal if the acoustic energy transmitted from the broadband BAW resonator contains spectral components at its predetermined resonant frequency.
