This article presents the design and performance of a terahertz on-chip coupled-grounded coplanar waveguide(GCPW) power combiner using a 50 μm-thick InP process.The proposed topology uses two coupled-GCPW lines at the end of the input port to substitute two quarter-wavelength GCPW lines,which is different from the conventional Wilkinson power combiner and can availably minimize the coverage area.According to the results obtained,for the frequency range of 210-250 GHz,the insertion losses for each two-way combiner and four-way combiner were lower than 1.05 dB and 1.35 dB,respectively,and the in-band return losses were better than 11 dB.Moreover,the proposed on-chip GCPW-based combiners achieved a compromise in low-loss,broadband,and small-size,which can find wide applications in terahertz bands,such as power amplifiers and signal distribution networks.
