Abstract |
This article presents the development of a
miniaturized differential coupler for UWB application using the Marchand balun
circuit in multilayer technology. The new technique employs double layer
substrate where on the bottom layer the two λ/4 short-circuited stubs with
balanced outputs are developed and on the top layer the λ/2 open-circuited stub
for unbalanced input is etched. These three transmission lines of the Marchand
balun circuit are capacitively coupled using overlapping microstrip lines. To
demonstrate this technique, a Marchand balun circuit using multilayer technology
is designed, simulated, fabricated and measured. The circuit size is about 2.8
mm × 3.7 mm × 0.63 mm excluding the feeding ports. The results from the
simulation and measurement show good agreement. |
