Abstract

Present solutions which regulate the operating temperature of apparatus used in information trans- mission employ mechanisms which decreased the power output level ofthe transmitter. Generally, this is accomplished by sensing the temperature of a crit- ical transmitter element, such as the power ampli- fier heatsink, and decreasing drive to the power ampli- fier using a negative feedback arrangement. In TDMA systems, temperature control is ohen effected by reducing the number ofslots for which the trans- mitter is enabled when the critical element temper- ature is exceeded. This method avoids transmitter power reduction which may be detrimental to the quality ofthe received transmission under marginal signal conditions. A disadvantage of limiting the num- ber of slots used in transmission is the reduction of data thru-put (e.g., the number of bits per second which are transmitted).
