Abstract :
A wideband three-way out-of-phase microstrip power divider based on the wideband phase inverter is presented. The measured return loss is <;-10 dB and the isolations are better than -19 dB from 2.5 to 5.37 GHz. The insertion losses are <;0.6 dB, and the output amplitude imbalances are <;0.9 dB. The phase differences (ang(S41)-ang(S42)) are within 180 ± 6°. The operation bandwidth of the proposed design achieves about 73.4% efficiency.
