“…In order to achieve more efficient power distribution, lots of different forms of multi‐way PDs have recently been invented. For instance, a design method for high‐isolation n‐way power combiners is proposed based on 2n + 1 port mode network in Reference . Although the high‐power four‐way PD with high isolation of 21 dB is realized in the band of 7.8 to 10.3 GHz, its power‐dividing ratio is still not released.…”

An exact closed-form design approach for a generalized high-power n-way Gysel power divider is proposed. The power divider could be designed to achieve an arbitrary power ratio with the flexible multiway application, arbitrary real terminated impedance, excellent isolation, and easy fabrication through both planar and threedimensional structures. Moreover, this improved power divider could maintain high power processing capacity through the coaxial cavity transmission line and grounding resistances. The exact analytical solutions related to ideal port matching and high isolation are obtained based on the circuit and transmission-line theory.To verify the proposed approach, a compact 3-way coaxial power divider with a pre-designed power ratio of 1:1.5:2 and four different real terminated impedances of 50, 55, 60, and 65 Ω is designed and fabricated. Excellent agreement is achieved between the simulated and measured results. Measurements from 4.7 to 5.7 GHz show that the return losses of all input and output ports are better than 15 dB. The maximum insertion loss is 0.5 dB, and the phase imbalance is approximately less than 6.1 . In addition, the isolation between any two output ports is better than 23 dB from 4.5 to 6 GHz. Meanwhile, the power handling capability can reach the maximum power of the commercial 50 Ω SMA connectors (2.098 kW).

“…This mechanism is known as load modulation. To eliminate the risk of unknown hazardous load modulation conditions occurring in the WTWPC and to guarantee all-condition stability, an isolated waveguide combiner based on magic-T [18] and a waveguide Gysel combiner [19] were developed to replace the WTWPC. However, these solutions significantly increase the combiner volume, while complicating the fabrication.…”

mm-Wave Waveguide Traveling-Wave Power Combiner Design Using an Equivalent Circuit Model

et al. 2019

The waveguide traveling-wave power combiner (WTWPC) falls into the category of asymmetrical non-isolated power combiners, and, therefore, the active load modulation occurring within the combiner was investigated. Proper manipulation of active load modulation gave rise to a two-step design method for the combiner. The first step formulated the specifications of the combiner in terms of active load impedance at its input ports, which determined the objective scattering parameters of the combiner, as well as the desired coherent excitation signals. The second step established a versatile equivalent circuit model to provide a mapping relation between the scattering parameters and the physical dimensions of the combiner. The proposed equivalent circuit method not only offered a close-to-reality description of the existing type of traveling-wave power combiners but also broke new ground for combiner variants that accommodate the more general driving amplifiers. A Q-band quasi-planar traveling-wave waveguide spatial combined amplifier was built to demonstrate the proposed method. The measured P −1dB bandwidth of the prototype was 6 GHz (33-39 GHz). INDEX TERMS Equivalent circuit, load modulation, traveling wave, mm-wave power amplifier, rectangular waveguide, waveguide probe, waveguide iris window.

This paper presents a new approach to design and implementation of a wideband microstrip radial power combiner with a planar structure in a way that it can be simply and inexpensively fabricated using a standard multilayer printed circuit board (PCB) technology. A 14-way power combiner with a two-octave bandwidth (1.5-6 GHz) is designed and fabricated on a three-layer PCB. Our measurements showed an amplitude and phase balance of ±0.75 dB and ±4.5 degrees, respectively, between the input ports. The main (output) port exhibited a reflection lower than −10 dB.
