Even though the two-stage Wilkinson N-way power divider is simple to design, realize and test, It has been used with strict restrictions in design and fabrication because it requires a very high impedance microstrip line, i.e., extremely low aspect ratio W/H or very thin line conductor width. To overcome this limitation in realizable characteristic impedance a quarter-wave length impedance transformer section between two lines is used. This research investigates the effect of adding quarter-wave lines impedance transformation to two-stage Wilkinson N-way power divider on the performance parameters.
