This work presents the design and simulation of a zinc oxide based thin film bulk acoustic resonator (TFBAR) bandpass filter for 2.6 GHz band applications. Third and fifth-order filters in ladder topology are designed and compared. The third-order filter has an insertion loss of 1.62 dB and return loss of 18.97 dB with a bandwidth of 80 MHz whereas the fifth-order filter has insertion loss, return loss, and bandwidth of 2.85 dB, 25.28 dB, and 60 MHz, respectively. With a central frequency of 2.67 GHz, the designed filter has applications in the 2.6 GHz (2500-2690 MHz) band, which has been identified by the International Telecommunication Union as a global frequency band for mobile broadband services. © 2016 IETE.
