RFID CONVERTER MODULE
First Claim
1. A module, comprising:
- a first receiver port configured to receive a reader transmit signal at a first frequency;
a first frequency converter configured to convert the reader transmit signal to a second frequency to provide a converted reader transmit signal, the second frequency differing from the first frequency;
a first transmit port configured to transmit the converted reader transmit signal to a tag;
a second receiver port configured to receive a tag transmit signal from a tag;
a second frequency converter configured to convert the tag transmit signal to the first frequency to provide a converted tag transmit signal; and
a second transmit port configured to transmit the converted tag transmit signal to the reader.

Abstract
A tag communication method includes providing a tag reader operating at a first frequency and having transmit and receive antenna ports, providing a frequency converter module having transmit and receive plugs adapted to directly mate with the transmit and receive ports, and directly mating the transmit plug with the transmit port and the receive plug with the receive port. A transmit signal at the first frequency is received from the reader by the converter module by way of the directly mated transmit plug and converted to a second frequency differing from the first frequency to provide a converted transmit signal which is transmitted to the tag. A receive signal is received from the tag at the second frequency and converted to the first frequency to provide a converted receive signal which is applied by the conversion module to the reader by way of the directly mated receive plug.

12. 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. - View Dependent Claims (13, 14, 15, 16, 17, 18)
