In this paper directional couplers with reduced size, by lumped elements, inverted microstrip, and broadside coupled lines at 61, 110, and 122 GHz center frequency and up to 156-GHz bandwidth have been designed. The couplers show an isolation up to 40 dB. Different SiGe BiCMOS technologies with 250-nm and 130-nm feature width and 5 to 7 metal layers have been used. The measurement results have been compared to simulation results and good agreement has been observed.
