RFID transmission circuitry including a transmission module producing a pulsed output, a first threshold circuit providing a pulsed output including only pulses whose amplitude exceeds a first threshold level, a second threshold circuit providing a pulsed output including only pulses whose amplitude exceeds a second threshold level, which is less than the first threshold level, a gate circuit operative to provide a logic output in response to each clock input, the logic output being responsive to the presence or absence of a signal input pulse thereat, a power amplifier receiving the pulsed output of the transmission module and the logic output from the gate circuit as a gain control input and providing an amplified output responsive to the gain control input and an antenna which is driven by an input derived from the amplified output.
