Abstract:
1. A high frequency switching circuit comprising: a high frequency switch having a first end and a second end, the first end connected to an input terminal for receiving a high frequency signal, and the second end connected to an output terminal for transmitting the high frequency signal to an antenna, the high frequency switch configured to be turned on or off by a control signal; and a capacitor having a predetermined capacitance and two ends, one of the ends connected to the output terminal and configured to connect with the antenna directly, and the other one of the ends connected to ground by a bonding wire configured to function as an inductor, the capacitor and the bonding wire forming a series resonant circuit; wherein an impedance of the capacitor and a wire length of the bonding wire are configured to provide the high frequency switch with an output impedance of approximately a short circuit in a high frequency band of the high frequency signal.
