Monitoring Junction Temperature of RF MOSFET under Its Working Condition Using Fiber Bragg Grating

Micromachines, 2022
When a high-power radio frequency (RF) metal oxide semiconductor field effect transistor (MOSFET) works in low-efficiency situations, considerable power is dissipated into heat, resulting in an excessive junction temperature and a likely failure. In this
