This paper presents the design of ladder-type filters based on film bulk acoustic wave resonator (FBAR) in Ku-band.The proposed\r\nFBAR filter has an insertion loss of -3 dB, out-of-band rejection of -12 dB and 3 dB bandwidth of 1.0GHz from 15GHz to 16GHz.\r\nBased on the characteristics of the FBAR filter, the expected characteristics of FBAR resonators are determined by using the 1D\r\nnumerical analysis. This design proves that it is possible to design a wide-bandwidth FBAR filter in Ku-band.
