Abstract
A circuit arrangement for transmitting and receiving radio signals includes an amplification device with an output for transmitting signals, an input for receiving signals and a supply line, and an antenna for transmitting and receiving signals. The antenna is connected to the output of the amplification device. The output of the amplification device is an input for signals received via the antenna, and the supply line is an output for received signals that are converted to the supply line by the amplification device.
Claims20
A circuit arrangement for transmitting and receiving radio signals, comprising:
- an amplification device including an output for transmitting signals, an input for receiving signals and a supply line;
- and
- an antenna for transmitting and receiving signals, the antenna connected to the output of the amplification device;
- wherein the output of the amplification device is an input for a signal received via the antenna, wherein the amplification device is for converting the signal received via the antenna into a converted signal, and wherein the supply line is an output for the converted signal.
A method for frequency conversion in an amplification device having an input for a supply current, a signal input and a signal output, comprising:
- applying a first signal to the signal input of the amplification device with nondiminishing amplitude;
- applying a second signal to the signal output of the amplification device;
- and
- converting the second signal into the supply current, including operating the amplification device in a supercritical range.
