“…The PD described in [16,17,18,19,20] showed advanced circular symmetry and their main ports were divided to more than 8 branches, which earned excellent transmission performance. But in [21,22,23,24,25], when the number of branches was reduced, the working band and transmission efficiency of PDs with similar structure were obviously constrained. The PDs mentioned above all exhibited that propagation direction bending, low impedance input, and high-power capacity demand often limit its bandwidth or lead to waveform distortion.…”

A novel compact 4-way ultra-wideband short pulse power divider (PD) based on coaxial waveguide is proposed in this paper. A nylon conical shell is inserted to replace the original transformer oil with an air block at the resonant place of PD to widen the working bandwidth. The junction of all inner conductors is smoothed to increase the fidelity and power capacity. The proposed PD is fabricated and tested. The results show that return loss is better than 12 dB from 191 MHz to 1.33 GHz. The amplitude loss is less than 10% and fidelity is more than 0.95 when input by impulse with full width at half maximum (FWHM) of 1.24 ns.

This article presents a 16‐way short pulse power divider (PD) with the same input and output impedance based on the transmission line transformer (TLT) principle. Different from the traditional multi‐channel PD composed of impedance tapered transmission lines and PDs in parallel structure, the novel 16‐way PD is cascaded by multi‐stages of series‐parallel structure, which avoids the process of impedance transformer and improves the compactness of the device, as well as the transmission efficiency. It was composed of four stages of the novel series‐parallel constructure converted from coaxial waveguide to microstrip line. And to control the energy dissipation, a unified ground of the output ports was built, and the short‐ended metal shell was loaded between every stage. This 16‐way PD was fabricated and measured. The measured return loss of the PD is less than −16 dB from 440 MHz to 6 GHz, and less than −10 dB from 270 MHz to 6 GHz. The measured peak gain is more than 0.83 when input by a Gaussian pulse with tFWHM = 250 ps (FWHM: full‐width half maximum).
