A multilayer coplanar waveguide low‐pass filter on an Si substrate fabricated by using MMIC technology is presented, and the performance is investigated experimentally and with electromagnetic simulations. The filter is a Chebyshev type consisting of three low‐impedance sections and two high‐impedance sections. The low‐impedance sections have a characteristic impedance of 3 Ω. The high‐impedance lines use a narrow center conductor mounted on top of the polyimide layers in order to achieve as high an impedance as possible (100 Ω). © 1998 John Wiley & Sons, Inc.
