  • 2015 IEEE. An ultra-wideband low-loss millimeter-wave Wilkinson power divider has been developed on a 0.18 m SiGe BiCMOS process. The miniaturization and low loss of the power divider are achieved by utilizing capacitive loading and a slow-wave CPW structure configured with floating metal strips periodically placed orthogonal to the CPW. The developed power divider has extremely wideband performance from DC to 67 GHz with less than 1 dB insertion loss from DC to 61 GHz, amplitude and phase imbalances less than 0.5 dB and 2 from DC to 67 GHz, respectively, and isolation greater than 15 dB across 37-67 GHz. At 60 GHz, the designed power divider has only 0.9 dB of insertion loss and better than 25 dB of isolation. The core chip size is 150 m 525 m.
