ABSTRACT:
An electronic circuit for a high-frequency switch for opening an antenna resonance circuit of an RFID system, wherein the high-frequency switch can be opened and closed by d.c. voltages, in which circuit a rectifier circuit generates the blocking voltage for opening the high-frequency switch from the high-frequency supply voltage, the rectifier circuit is designed such that it generates a blocking voltage whose value corresponds at least to the peak-to-peak value of the high-frequency voltage to be switched, the blocking voltage is conducted via the same electric connecting line via which the high-frequency supply voltage and a closing voltage are also conducted to the antenna of the RFID system, and a resistor is connected in parallel with each of the PIN diodes, which are series-connected with respect to direct current.
