Abstract
Thermal temperature sensors for power amplifiers are provided herein. In certain implementations, a semiconductor die includes a compound semiconductor substrate, and a power amplifier including a plurality of field-effect transistors (FETs) configured to amplify a radio frequency (RF) signal. The plurality of FETs are arranged on the compound semiconductor substrate as a transistor array. The semiconductor die further includes a semiconductor resistor configured to generate a signal indicative of a temperature of the transistor array. The semiconductor resistor is located adjacent to one end of the transistor array.
