Compact on-chip 90 GHz Bandpass filter Using Broadside-Coupled Meander line Resonator for Millimeter-wave Application

Abstract

In this paper, an on-chip 90 GHz bandpass filter using broadside-coupled meander line resonator is presented. The filter is designed using a 0.5um InP HBT technology for millimeter-wave application. The performance is extensively verified using an EM simulator of ADS. A transmission zero can be generated by changing the total length of the resonator and effectively controlled. By using capacitive feeding, the designed resonator generates one transmission pole at 90.3 GHz with insertion loss of −0.038 dB, and one transmission zero at 120.8 GHz with the rejection of −42.4 dB. The BPF chip area is 230um*191um2 including pads.
