COPLANAR 3dB QUADRATURE COUPLER A low loss coplanar waveguide 3dB power divider is described having high isolation between the output ports and low VSWR at the input port when used in a balanced circuit configuration. The power divider includes a 50 ohm coplanar waveguide input line and two 50 ohm coplanar waveguide output lines. The output lines are matched to the import line by 71 ohm quarter wavelength sections of coplanar waveguide lines. One output line is a quarter wavelength longer than the other. A quarter wavelength slot is cut in the input line center conductor, and a resistor is defined at the juncture of the input and output lines. Reflected power that would normally travel out the input port is terminated in the resistor.
