    摘要: A multi-mode RFID reader operates in both far field mode and near field mode. The multi-mode RFID reader includes a transmitter section, a receiver section, a transmit multiplexer and a receive multiplexer. Both the transmit multiplexer and the receive multiplexer are configurably coupled to a far field antenna structure and a near field coil structure. For far field operation, the transmit multiplexer provides an up-converted outbound signal to a far field antenna structure and the receive multiplexer provides an inbound signal to a receiver section. For near field operation, the transmit multiplexer provides an up-converted outbound signal to the near field coil structure and the receive multiplexer provides an inbound signal to the receiver section.

    摘要: Aspects of a method and system for enabling simultaneous FM transmitter and FM receiver functions using an integrated Bluetooth Local Oscillator Generator (LOGEN). A Bluetooth® LOGEN may be utilized to generate Bluetooth® signal that comprise (I) and (Q) components for use in Bluetooth® communication. The Bluetooth® LOGEN may then be utilized by a DDFS to generate FM radio (I) and (Q) signals for FM radio reception. The Bluetooth® LOGEN may also be utilized by a second DDFS to generate FM radio (I) and (Q) signals for FM radio reception. The Bluetooth® signals may be kept at the same frequency, or reduced in frequency, for use in clocking the DDFS. A frequency word may also be utilized to clock the two DDFS. The outputs of each DDFS may be a constant frequency while the inputs to each DDFS may vary in frequency.

    摘要: A real-time/non-real-time/RF IC includes first and second baseband processing modules, an RF section, a wireline interface, and a bus structure. The first baseband processing module converts real-time outbound data into real-time outbound symbols and converts real-time inbound symbols into real-time inbound data. The second baseband processing module converts non-real-time outbound data into non-real-time outbound symbols and converts non-real-time inbound symbols into non-real-time inbound data. The RF section converts the real-time outbound symbols into real-time outbound RF signals, converts real-time inbound RF signals into the real-time inbound symbols, converts the non-real-time outbound symbols into non-real-time outbound RF signals, and converts non-real-time inbound RF signals into the non-real-time symbols. The wireline interface couples the non-real-time outbound data, the non-real-time inbound data, the real-time outbound data, and/or the real-time inbound data to an off-chip wireline connection.

    摘要: A receiver architecture for canceling blocking signals in the receive path includes a low noise amplifier for receiving and amplifying an inbound RF signal to produce an amplified inbound signal, in which the inbound RF signal includes a modulated RF signal and a blocking signal, and a cancellation module for substantially canceling the blocking signal from the amplified inbound RF signal and substantially passing the modulated RF signal. The cancellation module cancels the blocking signal by generating an injection signal representative of the blocking signal, combining the blocking signal with the injection signal to produce an error signal, updating the injection signal based on the error signal and using the injection signal to cancel the blocking signal from the amplified inbound RF signal.
