Abstract
A novel design of compact dual-band equal power divider circuit for large frequency-ratio (greater than 3) applications is proposed in this paper. Topology of the circuit consists of two-section transmission-line transformers and a series RLC network for isolation. This power divider provides an equal power-dividing at two arbitrary frequencies which feature high center frequency-ratio. Besides, this power divider achieves good port matching and isolation. Theoretical derivations are presented and verified by measuring a 3-dB microstrip power divider operating at both 1 GHz and 4 GHz.
