Abstract

A novel small-size filtering power divider (PD) featured four-function integration is proposed. These four integrated functions are high-selectivity filtering, inherent DC block, high all-frequency isolation, and high-power applications. Using single-layer planar circuit technology, this proposed PD can be implemented easily. The measured results of a prototype show that it can operate at 2 GHz with a −10 dB matching bandwidth of 6% and all-frequency −15 dB isolation.
