Patent ID: 8260347

Claim:
A circuit for efficient wireless communication, comprising: a transmission communication port configured to couple to a single antenna; a reception communication port, separate from the transmission communication port, and configured to couple to the single antenna, and wherein both the transmission communication port and the reception communication port are configured to interface with the single antenna concurrently when the single antenna is coupled thereto; a signal generator configured to generate a transmission signal in one of a plurality of different transmission frequency bands; a plurality of amplifiers, wherein each one of the plurality of amplifiers is associated with a respective one of the plurality of frequency bands, and wherein the signal generator is configured to direct the transmission signal to the appropriate amplifier based on the frequency band in which the generated transmission signal resides; a plurality of transmission phase shift selection circuits respectively associated with the plurality of amplifiers, wherein each of the plurality of transmission phase shift selection circuits exhibits a unique impedance associated with the respective frequency band, thereby passing signal frequencies within the respective frequency band and rejecting signal frequencies outside the respective frequency band, wherein an output of each of the plurality of transmission phase shift selection circuits is connected to the transmission communication port; a plurality of reception phase shift selection circuits, wherein each one of the plurality of reception phase shift selection circuits are associated with one of a plurality of different reception frequency bands, and wherein each of the plurality of reception phase shift selection circuits exhibit a unique impedance associated with their respective reception frequency band, thereby passing signal frequencies within the respective reception frequency band and rejecting signal frequencies outside the respective reception frequency band; a plurality of low noise amplifiers, wherein each one of the low noise amplifiers is associated with a respective one of the plurality of reception phase shift selection circuits; and a demodulator configured to receive a signal from each of the plurality of low noise amplifiers, wherein the demodulator is configured to receive and demodulate the signals to produce received data.
