    • Second transistors working as temperature-monitoring elements are disposed in the vicinity of the respective first transistors (HBT cells) connected in parallel to amplify an RF signal and at positions where their thermal environments are substantially the same. Each of the second transistors is connected between its collector and its base to thereby constitute a diode through which the current rises as the temperature increases. The collectors of the second transistors are connected with a DC power supply through respective first resistors, and their emitters are grounded through respective second resistors. Further, their bases are connected with the bases of the respective first transistors through respective first inductors.
