Abstract :
Short-circuit series stubs realized in the signal conductor of an asymmetric coplanar stripline (ACPS) transmission line are investigated as a circuit element in order to achieve a significant size reduction of a MMIC Wilkinson divider. A simple ideal transmission line equivalent circuit is used to model the ACPS line/stub combination yielding good agreement with EM simulation. The stubs are then utilized to shorten the /spl lambda//4 transmission lines by approximately 35% in a Wilkinson divider application at 23 GHz.
