Publication number: 20050012393Abstract: The transceiver features a fast de-excitation circuit, by means of which the transceiver can be very quickly de-energized or de-excited after sending of signals. The fast de-excitation circuit can be realized in the simplest case as a controllable switch with series-connected resistor. The transceiver is thus ready to receive signals again very fast, i.e. in the range of a few oscillation periods. With bidirectional data communication between transceiver and transponder the danger of malfunctions is avoided or at least reduced to a minimum level.Type: ApplicationFiled: July 9, 2004Publication date: January 20, 2005Inventors: Mark Elliott, Christoph Kleiner, Wolfgang Reiml, Dieter Sass, Peter Turban, Herbert Zimmer
