In this paper, CPW transmission lines and Dual Behavior Resonator (DBR) filters implemented in SiGe BiCMOS 0.25-μm technology are presented. Three CPW lines, whose characteristic impedances are between 35 Ω and 80 Ω, exhibit attenuation loss lower than 0.7 dB/mm at 60 GHz. Two DBR filters based either on microstrip or on CPW transmission lines are compared. The filter with microstrip lines has already been measured and exhibits 11.6% of 3-dB relative fractional bandwidth (FEWmb) and 5.4 dB of insertion losses at 60 GHz. The second one is supposed to have similar performance with lower insertion loss (3.3 dB) and its measurement will be available for the conference.
