Abstract
An on-chip power divider with an extremely wide bandwidth is presented. The power divider was implemented in a TSMC 180 nm RF CMOS process. Measurements showed an absolute bandwidth of 68 GHz from 14 to 82 GHz with a matching condition of <;-10 dB, which was the fractional bandwidth of 141.7%. A very accurate bandwidth analysis using the theory of three coupled lines is provided. An insertion loss of 2.8-10.5 dB was measured across the bandwidth. The core size of the power divider is 0.2 × 0.73 mm.
