Title: The Innovations of Hendrik Roller
Introduction
Hendrik Roller is a notable inventor based in Dresden, Germany. He has made significant contributions to the field of wireless communication technology. His work primarily focuses on enhancing the efficiency and reliability of transceiver devices.
Latest Patents
Hendrik Roller holds a patent for an "Automatic power level control circuit for a transceiver device." This innovative circuit provides output power control for a transmitter device used in wireless LAN applications. The design allows for the detection of an output signal, which subsequently adjusts a corresponding control voltage of a Digital-to-Analog Converter (DAC) in the baseband section. The measurement of output power occurs during the first transmit cycle, with the DAC being adjusted after this cycle and before the next one begins. This method ensures reliable output level control with a minimal number of radio frequency components, enhancing the stability of the control loop due to the time-discrete control operation.
