Automatic power level control circuit for a transceiver device |
摘要 |
An automatic power level control circuit provides output power control of a transmitter device as used in wireless LAN applications in that an output signal is detected and a corresponding control voltage of a DAC in the base band section is corresponding adjusted. Preferably, the measurement of the output power is carried out during a first transmit cycle and the DAC is adjusted after completion of the first transmit cycle and prior to the begin of a subsequent transmit cycle. Thus, a reliable output level control is obtained with a minimum number of radio frequency components, wherein the control loop shows an enhanced stability due to the time-discrete control operation.
