Abstract: The present invention relates to a single chip-type Film Bulk Acoustic Resonator (FBAR) duplexer, which fulfills the required frequency characteristics, while allowing all the transmit and receive FBAR arrays to have the same effective coupling coefficients, thus enabling the transmit and the receive filters to be implemented as a single chip (or a die). The effective coupling coefficient of all the transmit and receive FBAR arrays is designed to have the value of 5.2 percent to 6.4 percent. The transmit filter are designed to achieve a desired frequency characteristics including optimizing the ladder topology and introducing common ground inductor disposed between the shunt resonators and the ground terminal.

Abstract: The present invention relates to a ladder-type bulk acoustic wave filter with a common ground inductor, which obtains high attenuation in a high frequency stop band adjacent to a pass band without the insertion loss degradation of the pass band, so that the ladder-type bulk acoustic wave filter is useful as a transmit filter. According to the present invention, the plurality of shunt resonators are commonly grounded through the inductor, so that zeros are generated due to the interaction between the stray capacitance of shunt resonators and the common ground inductor, thus improving attenuation characteristics in a high frequency stop band.
