Radio frequency data communications device

   
   

A radio frequency identification device comprises an integrated circuit including a receiver, a transmitter, and a microprocessor. The receiver and transmitter together define an active transponder. The integrated circuit is preferably a monolithic single die integrated circuit including the receiver, the transmitter, and the microprocessor. Because the device includes an active transponder, instead of a transponder which relies on magnetic coupling for power, the device has a much greater range.

Un dispositivo de la identificación de la radiofrecuencia abarca un circuito integrado incluyendo un receptor, un transmisor, y un microprocesador. El receptor y el transmisor juntos definen un transpondor activo. El circuito integrado es un monolítico escoge preferiblemente el circuito integrado del dado incluyendo el receptor, el transmisor, y el microprocesador. Porque el dispositivo incluye un transpondor activo, en vez de un transpondor que confíe en el acoplador magnético para la energía, el dispositivo tiene una gama mucho mayor.
