Abstract
A communication apparatus includes an antenna and a receive chain. The receive chain includes a switching transistor, and amplification transistor and a discharge transistor. The amplification transistor has a control terminal coupled to a current path terminal of the switching transistor. The discharge transistor has a current path coupled between the control terminal of the amplification transistor and a ground terminal. The discharge circuit is configured to discharge an intrinsic capacitance of the switching circuit when the switching transistor is in an off state.
