A W-band miniature power divider based on E-faced-folded magic-T junction

Abstract: A novel design of W-band power divider using E-faced-folded waveguide magic-T junction to realize the miniaturization is proposed in this paper. A stepped regular triangular prism and the stepped impedance transformer are utilized in order to obtain excellent performance. Besides, the performance of the E-faced-folded magic-T power divider is also improved by using short planes. The measured results show that the insertion loss of the power divider is better than 0.6dB and the return loss is better than 15dB. The measured average E-H isolation is better than 30dB from 92GHz to 100GHz range.

Micromachined W-band Eight-way Power Divider Based on Micro-coaxial Lines

Abstract: This paper presents a micromachined eight-way T-type power divider based on micro-coaxial lines. For ease of testing, two identical power dividers are placed in back-to-back configuration, and CPW to micro-coaxial line transitions are added at the input and output ports. The whole structure is directly measured using an on-wafer probe system. At 75–110 GHz, the measured return loss is better than 15 dB and the total insertion loss is 1–2 dB, showing excellent performance in terms of loss and phase balance. The divider can be widely used in power combined amplifiers and phased arrays.

Design of Ultra-Wideband T-junction Power divider Based on Rectangular Micro Coaxial Structure

Abstract: In this paper, two ultra-wideband T-junction power divider based on rectangular micro coaxial structure are proposed. One is a 3-dB power divider and the other is a 2:1 unequal power divider. The rectangular micro-coaxial structure has the advantages of small size, ultra-wideband and small transmission loss, so the power divider based on this structure has good performance. The center conductor is slotted to realize device miniaturization. The simulation results show that the transmission loss is less than 0.3 dB from 60 GHz to 110 GHz in both dividers. And the return loss of 3-dB power divider and 2:1 unequal power divider are better than 19.5dB and 14dB respectively.
