AbstractIn this paper, a tunable balanced-to-balanced in-phase filtering power divider (FPD) is designed, which can realize a two-way equal power division with high selectivity and isolation. A differential-mode (DM) passband with a steep filtering performance is realized by applying microstrip stub-loaded resonators (SLRs). Meanwhile, six varactors are loaded to the SLRs to achieve the center frequency (CF) and bandwidth adjustment, respectively. U-type microstrip lines integrated with stepped impedance slotline resonators are utilized as the differential feedlines, which suppress the common-mode (CM) intrinsically, making the DM responses independent of the CM ones. A tuning center frequency from 3.2 to 3.75 GHz and a fractional bandwidth (12.1–17.6%) with more than 10 dB return loss and less than 2.3 dB insertion loss can be achieved by changing the voltage across the varactors. A good agreement between the simulated and measured results is observed. To the best of authors' knowledge, the proposed balanced-to-balanced tunable FPD is first ever reported.

Circuit Technology

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.
