Compact dual-band five-way Wilkinson power divider
A compact dual-band five-way Wilkinson power divider with good RF performance is presented. Two-section impedance transformers are utilised to obtain the dual-band function. To facilitate assembling the isolation resistors among outputs, a second layer is introduced. The proposed power divider works at 0.915 and 2.45 GHz with small phase and magnitude imbalances.
