Abstract
In accordance with an exemplary embodiment, a system comprising a transceiver, a sensor and a controller is provided. The sensor is coupled to an electrical component in the transceiver and is configured to measure a thermal load on the electrical component. The controller is configured with a predetermined threshold(s), and is configured to reduce the voltage and/or current bias point, in the power amplifier, in response to the thermal load measurement being greater than the predetermined hot threshold or less than a predetermined cold threshold. The system provides an inexpensive transceiver system solution to the problems of shedding thermal load under high temperatures and undesirable gain increases, loss of stability and power consumption increases at low temperatures, and can be incorporated into new systems or adapted to legacy systems.
