DEVICE FOR REDUCING GENERATION OF HEAT OF TERMINAL AND METHOD THEREFOR, ESPECIALLY REGARDING TO INCREASING BATTERY USAGE TIME, REDUCING CALORIC VALUE, AND PREVENTING NOISE AMPLIFICATION IN TRANSMITTING SIGNAL BAND

摘要

Purpose: a device generates a hot terminal and a kind of method for reducing, and is arranged to increase the battery consumption rate time thus, reduces calorific value, prevents noise amplification according to receiving sensitivity suitably one power amplifier of on and off in a transmitting signal band. Construction: a controller (210) adjustment transmitting data enters analog signal, generates first and second control signal according to the receiving sensitivity for receiving data. One automatic gain amplifier (220) receives analog signal and is used for amplified analog signal. The harmonic component for the power source that one RF (radio frequency) SAW filter (230) exports from automatic gain amplifier removal signal. If opened by first control signal, a power amplifier (240) exports from RF SAW filters (230) amplified signal and passes through strip antenna transformation amplified signal. One switch sections (250) are connect with power amplifier (240) in parallel, are used to be exported according to the control of second control signal from RF SAW filters (230) flowing or interrupt signal.
