A broadband and compact inductorless active power divider is presented in this letter. By using the Darlington cell, the proposed monolithic active power divider demonstrates broad and flat bandwidth of output 1 dB compression point over the 3 dB bandwidth. The gain-bandwidth performance, input matching, and device ratio of the Darlington cell are presented to achieve broad bandwidth. The proposed active power divider exhibits a potential for the high speed transmissions due to its broad bandwidth, low amplitude/phase errors, low and flat group delay.
