A new 3-dB power divider for millimeter-wavelengths

This paper presents a new type of 3-dB power divider that achieves wide-ban d, low-loss, and symmetric power division. In the paper, we discuss the des ign considerations and present results of measurements at 10 and 100 GHz, T he power divider symmetry is examined as a function of the termination load s mismatch, The simplicity of the presented divider makes it very suitable for application at millimeter and submillimeter bands. The predicted and th e measured performance are in very good agreement.
