Abstract:
1. An apparatus for use in a tag security system having a tag, comprising: a frequency converter module configured to be coupled to (i) a transmit plug directly mated with a transmit antenna port of a tag reader operating at a first frequency to provide a directly mated transmit plug, and (ii) a receive plug directly mated with a receive antenna port of the tag reader to provide a directly mated receive plug; the frequency converter module having a transmit frequency converter for receiving a reader transmit signal at the first frequency from the tag reader by way of the directly mated transmit plug, converting the reader transmit signal to a second frequency differing from the first frequency to provide a converted reader transmit signal, and transmitting the converted reader transmit signal to a tag; and a receive frequency converter for receiving a tag transmit signal at the second frequency from the tag, converting the tag transmit signal to the first frequency to provide a converted tag transmit signal, and applying the converted tag transmit signal to the tag reader by way of the directly mated receive plug.
