Real-time. In-circuit Temperature Sensing of an X-Band GaN Power Amplifier
A 10-watt X-band GaN power amplifier has been designed as a testbed to study amplifier temperature under a variety of biases and input drive levels using gate-resistance thermometry. Real-time, in-circuit temperature sensing is demonstrated and discussed for a range of biases and input levels.
