An embodiment of the present invention provides an apparatus, comprising a
radio frequency identification transceiver adapted for self jammer
suppression. The transceiver may further comprise a phase shifter and
variable attenuator/variable amplifier adjusted to minimize the power
injected into a receive chain by the self jammer. In an embodiment of the
present invention the present transceiver may further comprise at least
one RF peak power detector to determine the power injected into the
receive chain.
