Rf device

Abstract

In an embodiment, a circuit includes a first input terminal configured to be coupled to a first terminal of a first capacitor, a second input terminal configured to be coupled to a second terminal of the first capacitor, a balun including a primary inductor and a secondary inductor, and a second capacitor. The primary inductor includes a first terminal coupled to the first input terminal, a second terminal coupled to the second input terminal, a first inductive portion coupled between the first terminal of the primary inductor and a first intermediate terminal, a second inductive portion coupled between the second terminal of the primary inductor and a second intermediate terminal, and a third inductive portion coupled between the first and second intermediate terminals. The secondary inductor includes a first terminal coupled to a ground terminal. The second capacitor is coupled between the first and second intermediate terminals.
