Abstract: A semiconductor apparatus includes multiple field effect transistors provided between an antenna terminal to be connected to an antenna and multiple external terminals through which RF signals are capable of being supplied and a voltage generating circuit. When the field effect transistors provided between one of the multiple external terminals and the antenna terminal are turned off, the voltage generating unit charges a capacitor via a resistor circuit by switching the polarity of the RF signal to be supplied to the other external terminal with respect to the control signal and outputs a voltage based on a sum of the charge voltage and the voltage of the control signal as the gate drive voltage. The resistor circuit includes a first resistor including positive temperature characteristics and a second resistor including negative temperature characteristics.

Abstract: Bidirectional detection is performed with a suppressed increase in return loss at an output terminal. A bidirectional coupler includes a detection port, a main line connected to a first port and a second port, a sub-line, a termination circuit, a switch circuit that switches each of one end and another end of the sub-line to the termination circuit or the detection port, and a matching network disposed between the switch circuit and the detection port and including at least one of a first variable capacitor, a first variable inductor, or a first variable resistor. In a first mode for detecting a first signal, the switch circuit connects the one end of the sub-line to the detection port, and connects the other end of the sub-line to the termination circuit.
