Design of 60GHz Millimetre-Wave Integrated SIR-MH Microstrip Bandpass Filters on Bulk CMOS

In this paper challenges of integrating millimetre-wave bandpass filters on CMOS are discussed. A new compact 57-66 GHz 4th-order cross-coupled SIR-MH bandpass filter was designed and fabricated on 0.13 mum bulk CMOS. Both simulation and measurement results are presented. The measurement results show 8.5 GHz bandwidth from 58-66.5 GHz, 5.9 dB insertion loss, and better than 10 dB return loss over the whole passband. The filter reported in this paper has higher selectivity and is 80 percent smaller than other designs reported in the literature. This paper demonstrates the feasibility of building compact millimetre-wave integrated bandpass filters on CMOS.
