Abstract: An apparatus can include radio-frequency transceiver circuitry to transmit and receive radio-frequency signals in a first communications band and in a second communications band. The apparatus can further include a diplexer coupled to the radio-frequency transceiver circuitry. The diplexer can have terminals connected to a first path that conveys the radio-frequency signals in the first communications band and a second path that conveys the radio-frequency signals in the second communications band. The diplexer terminals can also connect to a first switch interposed in the first path and a second switch interposed in the second path.

Abstract: A method and apparatus for cancelling an interference in a received signal. The apparatus may include a plurality of receivers and one or more transmitters. The first receiver is configured to process a received signal. The first receiver includes a mixer to down-convert the received signal using a first local oscillator signal having a first frequency. The received signal includes a wanted signal and an unwanted signal. The second receiver is configured to process the received signal and generate an interference reference signal. The second receiver includes a mixer to down-convert the received signal using a second local oscillator signal having a second frequency. The apparatus includes an interference canceller configured to cancel, in a digital domain, at least in part interference caused by non-linear characteristics of the first receive chain in a presence of the unwanted signal from the down-converted received signal by the first receive chain.

Abstract: An apparatus can include sampling circuitry and processing circuitry coupled to the sampling circuitry. The processing circuitry can predict a next sample of an input signal and determine a predicative portion of the next sample of the input signal. The processing circuitry can subtract the predicative portion from the input signal to determine a non-predicative portion of the input signal and provide the non-predicative portion to the sampling circuitry for sampling.
