In this article, a wideband filtering power divider using vertically installed planar (VIP) circuit is proposed, where three-line coupled structures are introduced to realize filtering responses. The even-odd mode analysis method is applied to assess the electrical performance of the whole structure. The simulated and measured results demonstrate that the proposed design has a wide operation bandwidth (>103%), low insertion loss (<0.6 dB) and good isolation (>15.2 dB). Moreover, the amplitude imbalance and phase imbalance are less than 0.2 dB and 0.5 , respectively.filtering power divider, vertically installed planar (VIP) circuit, wideband

“…Power dividers (PDs) are crucial RF/microwave components that can split an input signal into two equal power and in‐phase signals. Wilkinson PDs and Gysel PDs are the most popular topologies, which have been widely used in wireless communication systems 1–3 . These two kinds of PDs have good in‐band isolation and impedance matching.…”

“…Power dividers [25][26][27][28][29][30][31] have functions of power dividing or power combining, which have been widely used in radar systems and wireless communication such as high power amplifiers, mixers, and antenna arrays, which are also essential components in vector network analyzer. In recent years, new power dividers with multi-section combined/metamaterial structures, multi-band and multifunction have been developed with the requirement of integration and miniaturization for microwave circuits.…”

In this article, a matched branch line-loaded negative group delay (NGD) circuit without resistor is presented firstly, and then an Wilkinson power divider with NGD characteristic is implemented by integrating the NGD circuit and the power divider by using self-packaged suspended coplanar waveguide (SCPW) technology. The self-packaged SCPW power divider with NGD characteristic has been fabricated, and the design has been demonstrated by measurement, which indicates that the proposed power divider with NGD characteristic has a measured signal attenuation (S 21 ) of 10.92 dB, a S 11 attenuation of 32.1 dB, an NGD time of À2.42 ns, and an isolation of no less than 39 dB at the center frequency, while simple circuit topology, self-packaging and compact circuit size have also been achieved.

This letter proposes a N‐way planar power divider/combiner using a combination of a Gysel power divider and a ring coupler. This innovative approach enables the realization of a fully planar multiway (>2) Gysel power divider. By replacing the common point of the conventional Gysel power divider with a ring coupler, the entire symmetrical divider can be implemented on a two‐layer printed circuit board. To validate the design concept, an eight‐way planar power divider is designed, fabricated, and tested. Experimental results obtained within the frequency range of 5.10–7.25 GHz (34.8% fractional bandwidth) demonstrate excellent performance. The insertion loss is below 1.24 dB, the input port return loss exceeds 12.65 dB, the output ports exhibit return loss greater than 14.83 dB, the isolation exceeds 22.41 dB, and the maximum measured phase imbalance is within ±2.7°.
