A simple circuit was constructed to apply power up to 40dBm. However, when the input power was 27dBm, the phenomenon of gain extension occurred. From the results, should I see 27dBm as the MOSFET being broken down? Can i see the breakdown phenomenon in the simulation as well? thank you

A tsmc nmos mosfet was used, and power was input to the drain up to 40dBm or more to design the switch. However, the mosfet gains gain after a power input of more than 27dBm. I am not able to understand this phenomenon. Upvote 0 Downvote
