Abstract
An electrical circuit (200) having an input terminal (201), an output terminal (202), and a signal common (203) is preferably used to attenuate an electrical signal. The electrical circuit (200) comprises four impedance elements (205-208) and an impedance transformer (210). A first impedance element (205) is coupled between the input terminal (201) and a first node (212), while a second impedance element (206) is coupled between the first node (212) and the output terminal (202). A third impedance element (207) is coupled between the input terminal (201) and the output terminal (202), while a fourth impedance element (208) is coupled between a second node (213) and the signal common (203). The impedance transformer (210) is coupled between the first node (212) and the second node (213) to complete the electrical circuit (200).
