    摘要： A cellular telephone IC includes a baseband processing module, an RF section, an audio codec, a keypad interface, a memory interface, and a display interface. The baseband processing module and RF section function to convert an outbound voice signal into an outbound RF voice signal, to convert an inbound RF voice signal into an inbound voice signal, to convert outbound data into an outbound RF data signal, and to convert an inbound RF data signal into inbound data. The audio codec section converts inbound analog voice signals into the inbound voice signals and converts the outbound voice signals into outbound analog voice signals. The keypad interface produces the outbound data based on received inputs. The display interface provides the inbound data to an off-chip display.

    摘要： An adjustable antenna interface includes a single-ended to differential conversion circuit, an adjustable impedance matching circuit, an RF differential switch, and an input. The single-ended to differential conversion circuit converts inbound RF signals from single-ended signals to differential signals and converts outbound RF signals from differential signals to single-ended signals. The adjustable impedance matching circuit provides an impedance based on an impedance control signal. The RF differential switch provides the differential outbound RF signals from the IC to the single-ended to differential conversion circuit in accordance with a first antenna control signal and provides the differential inbound RF signals from the single-ended to differential conversion circuit to the IC in accordance with a second antenna control signal. The input receives the first antenna control signal, the second antenna control signal, and the impedance control signal from the IC.

    摘要： A far field radio frequency identification (RFID) reader includes a baseband processing module, a transmitter section, and a receiver section. The receiver section includes a low noise amplifier module, a down conversion module, and a current mode blocking circuit. The low noise amplifier module amplifies an inbound RF signal to produce an amplified inbound RF signal. The down conversion module converts the amplified inbound RF signal into the inbound baseband signal. The current mode blocking circuit substantial compensates for a blocking current component of the baseband inbound signal and passes, substantially unattenuated, a signal current component of the baseband inbound signal.

    摘要： A multi-mode RFID tag includes a power generating and signal detection module, a baseband processing module, a transmit section, a configurable coupling circuit, and an antenna section. In near field mode, the configurable coupling circuit is operable to couple the transmit section to a coil or inductor in the configurable coupling circuit to transmit an outbound transmit signal using electromagnetic or inductive coupling to an RFID reader. In far field mode, the configurable coupling circuit is operable to couple the transmit section to the antenna section, and the multi-mode RFID tag then utilizes a back-scattering RF technology to transmit the outbound transmit signal to RFID readers.
