Abstract
A wireless communication device and a filter are provided. The filter has an input end and an output end and includes a first energy storage element, a first series resonant circuit, a second series resonant circuit, a first parallel resonant circuit and a second parallel resonant circuit. The first and the second series resonant circuits respectively have a first capacitor and a first inductor connected in series. The first and the second parallel resonant circuits respectively have a second capacitor and a second inductor connected in parallel. The first series resonant circuit and the first parallel resonant circuit are electrically connected in cascade between a first end of the first energy storage element and a ground, and the second series resonant circuit and the second parallel resonant circuit are electrically connected in cascade between a second end of the first energy storage element and the ground.
