NDLI: Theory and design of phase-inverted balanced coupled-line DC-blocker

Content Provider	IET Digital Library

Abstract	A planar DC-blocker suitable for differential mode signalling applications is designed and fabricated. The theory of this component is explained in a new form which utilises the wave scattering transfer matrix. The proposed interpretation of the transfer matrix is most suitable for series (cascade) elements like DC-blockers. In addition to the theoretical enhancement, design of a compressed balanced DC-blocker inserted through a shielded broadside coupled stripline (SBCSL) transmission line (TL) is presented. The return loss of better than 10 dB is obtained at 50-ohm differential-mode input ports of the fabricated DC-blocker in the entire frequency range of 5.6–8.4 GHz. The other achievement of this paper is design and fabrication of a wideband substrate-integrated waveguide (SIW)-mediated balun structure for single-ended measurement of a balanced SBCSL component. The fabricated balun exhibits a nearly perfect coaxial-mode to coupled-stripline differential-mode conversion in the full range of 5–9 GHz. The presented balun is successfully utilised to derive the scattering parameters (S-parameters) of the fabricated balanced SBCSL DC-blocker.
