Abstract
Output terminals (o, o) of a differentially excited transmitting circuit (TC) are connected through matching capacitors (MC, MC) to connecting terminals of the oscillatory circuit antenna (OCA) on the other side said connection terminals are directly connected to input terminals of a receiving circuit (RC). Each of the input terminals (i, i) of the receiving circuit (RC) is connected to an earthing terminal (m) of the integrated transceiver circuit (TRC) through a corresponding undervoltage-protection diode (UPD, UPD) determining a lower potential value of a received signal and a corresponding overvoltage-protection diode (OPD, OPD) determining an allowed upper potential value of the received signal exceeding said lower potential value by the highest possible voltage still allowable by the integrated transceiver circuit (TRC). The highest allowable voltage amplitude of the received signals supplied to the input of the receiving circuit (RC) practically equals the highest possible voltage, which is still allowed by the integrated receiver circuit, thus exceeds energization voltage.
