The main disadvantage of the circuit is relatively narrow band of operation, which gains more on importance when ultra wide band solutions are required. The divider/combiner is used to combine the power of multiple transistors in an amplifier or antennas in a system, or divide the power among channels in a receiver. I NTRODUCTION The Wilkinson power divider is often made in microstrip or stripline form and is in common use in RF design, since it was introduced quite a lot years ago. Keyword: wilkinson powerd divider, combiner, tapering, power amplifier I. The limiting factor of this solution is the insertion loss. Such a combiner is broadband and works from 0.5 up to 3.5 GHz. 0 0493031426984, Short Abstract - This paper introduces a hybrid wideband architecture of the Wilkinson divider with tapered line and compares it with two-stage architecture.
