Abstract:
A transmit output controlling circuit of a wireless mobile communication system comprising:a demodulating portion for detecting an immediate frequency of a receive information induced through an antenna and passing through a duplexer portion; a receive sensitivity measuring portion for detecting a receive sensitivity level of the immediate frequency signal detected by the demodulating portion; a controller for receiving data from the demodulating portion and outputting a receive sensitivity data, a timing control signal and a transmit power control signal; a transmit signal control a receive sensitivity data into a transmit signal according to the receive sensitivity data and the timing control signal from the controller; a transmit output amplifying portion for amplifying the transmit signal from the transmit signal control; and, a transmit power control for controlling an amplification factor of the transmit output amplifying portion according to the control signal from the controller.
