Abstract :
The design of a broadband coplanar waveguide (CPW) Marchand balun fabricated using a photoimageable thick-film process is described. A multilayer coupling structure is employed to obtain a tight coupling. The technique is suitable as a low cost means of fabricating balanced mixers and modulators, with the balun requiring no bond-wires or through-substrate vias. The balun operates from 2 to 9 GHz with an excellent performance
