1. A method of providing or operating a switching module comprising:
providing a first input terminal of the switching module;
providing a second input terminal of the switching module; and
providing an output terminal of the switching module configured to output a radio-frequency component of an input signal received on the first input terminal or the second input terminal in response to the input signal including a positive direct-current voltage;
providing a first transistor having a drain directly coupled to the first input terminal via a first capacitor, a gate coupled to the first input terminal via a first resistor, and a source coupled to the output terminal;
providing a second transistor having a drain directly coupled to the second input terminal via a second capacitor, a gate coupled to the second input terminal via a second resistor, and a source coupled to the output terminal;
providing a third transistor having a drain coupled to the first input terminal, a gate coupled to the second input terminal via the second resistor, and a source coupled to a ground terminal of the switching module; and
providing a fourth transistor having a drain coupled to the second input terminal, a gate coupled to the first input terminal via the first resistor, and a source coupled to the ground terminal.
