Abstract
A space-efficient broadband balun (). The balun () includes a first mechanism () for receiving an input signal () having an undesirable component. A second mechanism () rejects the undesirable component via a waveguide transition (). In a specific embodiment, the undesirable component is a common mode component. The first mechanism () includes an input microstrip waveguide (). The waveguide transition () is a single microstrip-to-slotline transition () from the input microstrip waveguide () and to a slotline () in a ground plane () of the microstrip waveguide (). The slotline () is terminated at a first end () via a wedge () in the ground plane (). A second end () of the slotline () provides an output of the balun (). The input signal () includes a first input signal () and a second input signal (), which are input at opposite ends () of the input microstrip waveguide (). The first input signal () and the second input signal () have a desired differential mode component and an undesired common mode component.
