Abstract :
A multilayer coplanar waveguide lowpass filter on a GaAs realised by using multilayer MMIC technology is presented and the performance is investigated with electromagnetic simulations. The filter is a Chebyshev type employing 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 centre conductor mounted on top of the polyimide membrane layers in order to achieve as high an impedance as possible (100 Ω)
