A compact DVB-H (digital video broadcasting- Handheld) Marchand balun using coplanar waveguide (CPW) coupling structure is presented. The proposed structure combines a double sided meandered CPW Marchand structure with lumped elements. Having the vertical coupling of meandered CPW Marchand structure, wide bandwidth for DVB-H band (470-710 MHz) is achieved. Also, lumped elements are used to reduce the physical length of the coupling meandered lines. The proposed DVB-H balun is fabricated on FR-4 board and both simulated and measured results are presented to illustrate its performance.
