A novel ultra-wideband (UWB) coaxial-waveguide power divider is presented. The design approach for the presented power divider has been developed; and a four-way UWB coaxial-waveguide power divider has been designed, fabricated and measured. The measured results show good agreement with the simulated ones.Introduction: Waveguide-based power dividers have been widely used in microwave and millimetre-wave circuits and communication systems because of their low insertion loss, wide bandwidth and high power capability. Several waveguide-based power dividers/combiners, such as rectangular waveguide power dividers, radial waveguide power dividers and coaxial waveguide power dividers, have been studied and good performance reported [1][2][3][4][5]. In addition, ultra-wideband (UWB) devices and circuits have been developed greatly, and various broadband and UWB power dividers have been presented and studied [6 -8]. However, few waveguide-based UWB power dividers have been developed.A novel UWB coaxial-waveguide four-way power divider is developed. This four-way coaxial power divider employs a coaxial taper transition, an oversized coaxial waveguide and four coaxial probes. A step at the inner conductor has been used to change the electric field orientation from radial to axial, which can make the output ports and the input port in the same direction. Compared with the structure shown in [5], the proposed power-dividing structure may be easier to construct than the active power-combining system. The proposed coaxial-waveguide power divider has been designed, fabricated and measured. Experimental results show that the proposed coaxial-waveguide power divider has the advantages of wide bandwidth, excellent input impedance matching, low insertion loss and flat group delay within the UWB passband.

This article summarizes recent advances in the art of power splitter designs. Diverse design concepts and techniques proposed in recent years are introduced, mainly focusing on the out‐of‐phase power splitters, in‐phase power splitters, filtering power splitters, and high‐power waveguide power splitters. Because of the popularity of balanced circuits, out‐of‐phase power splitters are heavily demanded. The double‐sided parallel‐strip lines (DSPSLs), with the frequency‐independent out‐of‐phase characteristics, are attractive transmission lines for wideband out‐of‐phase power splitter designs. The design methods based on DSPSL for various power splitting responses have been presented, including single‐ and dual‐band, wideband, arbitrary power division ratios. Then, the research on in‐phase power splitters are addressed, focusing on dual‐band operation, arbitrary power division ratios, multiway division, reconfigurable responses, and size miniaturization. The four typical methods for achieving dual‐band operation and five methods for realizing unequal power division ratios are presented. In addition, some techniques for multiway power splitters and reconfigurable power dividers are introduced. As for size reduction techniques, the LTCC and MMIC fabrication processes are introduced and example designs are included. Later, the concept of filtering power splitters is introduced. The power splitters and bandpass filters are combined together to form dual‐function devices with both power splitting and filtering functions. The responses of equal and unequal power division ratios as well as dual‐band operation are presented with the associated design techniques. Finally, coaxial waveguide power splitters are introduced, which are suitable for high‐power millimeter‐wave applications. Various oversized coaxial waveguide structures and probe array arrangement are presented for multioutput applications. Furthermore, some advances on radial waveguide spatial power splitters are addressed and the typical examples are included.

A four‐device broadband solid‐state power amplifier, which is based on radial waveguide power‐dividing/combining circuit, has been investigated in this work. The fabricated power amplifier combining four monolithic microwave integrated circuit power amplifiers shows a 12–16.6 dB small‐signal gain over a broadband from 6 to 14 GHz. The measured maximum output power at 1 dB compression is 25.6 dBm at 10 GHz, with a high power‐combining efficiency of 96%. © 2008 Wiley Periodicals, Inc.
