Abstract :
This research reveals the realization of 5.4 GHz radio frequency bandpass filter utilizing film bulk acoustic wave resonator (FBAR) technology. It can be applied to wireless sensor network systems. Furthermore, it can also be application for wireless 802.11 n and 4 G-WiMAX system. In this paper, the 5.4 GHz filter has been demonstrated, which has central frequency of 5406 MHz, bandwidth of 70 MHz, insertion loss of -10 dB, return loss of -18 dB, and stopband attenuation of -36 dB, and size of 0.74 mm × 0.42 mm.
