ABSTRACT:
A radio transmitter power amplifier is connected to a driver circuit whose drive power determines the output power of the power amplifier. Direct current is supplied to the driver circuit under the control of a temperature control circuit which compares a temperature indicative voltage with a voltage indicative of the direct current drawn by the power amplifier. If the power amplifier direct current is above a desired level for a given temperature, the control circuit reduces the direct current supplied to the driver circuit, and hence reduces the output power of the power amplifier. If the power amplifier direct current is below a desired level for a given temperature, the control circuit increases the direct current supplied to the driver circuit, and hence increases the output power of the power amplifier.
