Patent abstract
In a power amplifier, techniques are provided for protecting the power amplifier from temperature extremes resulting from conditions such as load mismatches. After sensing the temperature of the power amplifier, the operation of the RF power amplifier is controlled accordingly. In one example, the power amplifier is shut down when the sensed temperature reaches a threshold value, which can be set to a value just below the point where permanent damage would occur. In another example, when a threshold temperature is reached, the operation of the power amplifier is changed, to prevent the temperature of the power amplifier from rising to a level that would damage the power amplifier.
