Description
Summary:In this letter, we propose an N-way unequal power division Wilkinson power divider (PD) with physical output port separation. These PDs employ isolation impedances at arbitrary positions within quarter-wave-long transmission lines, and hence both electrical isolation and physical separation can be obtained between output ports. Design equations are derived, meeting the impedance matching and isolation requirements of the PD. The fabricated 2-way (1:2) and 3-way (1:2:1) PDs operating at 2.0 GHz exhibit excellent insertion loss, return loss, and isolation performance with the output ports physically separated.
