A reduced-size, low-cost, low insertion loss power divider operating over a very broad bandwidth from 57-86GHz is designed, manufactured, tested, and presented in this paper. The proposed design is fabricated in a glass-substrate IPD (integrated passive device) technology and has a chip area of 0.435×0.36 mm2. A size-reduction of 33% compared to a conventional microstrip Wilkinson power divider has been achieved by using high-impedance modified coplanar waveguide (M-CPW) transmission lines, which are loaded at their ends with microstrip open-circuited stubs. The measured results showed an insertion loss of less than 0.5 dB over a frequency range of 50-67 GHz; the EM simulation results showed an insertion of less than 1.4 dB loss over a frequency range of 50-90 GHz. The proposed design is well suited for low-cost system-in-package (SiP) radio front-ends for multiband 60/70/80-GHz high data rate wireless communications systems.
