Amplification circuit

An amplification circuit, comprising:

• a first signal terminal, configured to receive a radio frequency signal;
• a second signal terminal, configured to output an output signal corresponding to the radio frequency signal;
• and
• a first path circuit, comprising:
• a first radio frequency switch, configured to selectively receive the radio frequency signal, and comprising a first terminal coupled to the first signal terminal, and a second terminal;
• an electrical overstress circuit;
• a low-pass filter, coupled in series with the electrical overstress circuit between the second terminal of the first radio frequency switch and a first reference voltage terminal, and configured to form a low-frequency conduction path to discharge electrical charges through the low-frequency conduction path when an electrical overstress event occurs;
• a high-pass filter, coupled in parallel with the electrical overstress circuit;
• and
• an amplifier circuit, configured to amplify the radio frequency signal, and comprising a first terminal coupled to the second terminal of the first radio frequency switch, and a second terminal coupled to the second signal terminal.
