    摘要： A receiver includes an antenna interface, a frequency translation bandpass filter (FTBPF), a sample and hold module, and a down conversion module. The antenna interface is operable to receive a received wireless signal from an antenna structure and to isolate the received wireless signal from another wireless signal. The FTBPF is operable to filter the received wireless signal to produce an inbound wireless signal. The sample and hold module is operable to sample and hold the inbound wireless signal in accordance with an S&H clock signal to produce a frequency domain sample pulse train. The down conversion module is operable to convert the frequency domain sample pulse train into an inbound baseband signal.

    摘要： A portable computing device includes a radio frequency (RF) wired link, a core module, and a plurality of multi-mode RF units. When one or more of the multi-mode RF units are supporting a high-speed data communication, the core module is operable to detect a blocker that is adversely affecting the high-speed data communication. The core module is further operable to determine whether a radiation pattern alternative for the high-speed data communication will reduce the adverse affects on the high-speed data communication. When the radiation pattern alternative for the high-speed data communication will reduce the adverse affects on the high-speed data communication, the core module is further operable to enable the radiation pattern alternative. The one or more multi-mode RF units are operable to adjust at least one of transmission and reception of the high-speed data communication in accordance with the radiation pattern alternative.

    摘要： A receiver includes a bandpass filter module, a sample and hold module, a discrete time bandpass filter module, a discrete time notch filter module, a combining module, and a conversion module. The bandpass filter module filters an inbound wireless that includes a desired signal component and an undesired signal component. The sample and hold module is operable to sample and hold the filtered inbound wireless signal to produce a frequency domain sample pulse train. The discrete time bandpass filter module bandpass filters the frequency domain sample pulse train to produce a bandpass filtered sample pulse. The discrete time notch filter module notch filters the frequency domain sample pulse train to produce a notched filtered sample pulse. The combining module combines the bandpass filtered sample pulse and the notched filtered sample pulse to produce a filtered inbound signal. The conversion module converts the filtered inbound signal into an inbound baseband signal.

    摘要： A Voice-Data-RF IC includes a baseband processing module, an RF section, and an interface module. The baseband processing module converts an outbound voice signal into an outbound voice symbol stream, converts an inbound voice symbol stream into an inbound voice signal, converts outbound data into an outbound data symbol stream, and converts an inbound data symbol stream into inbound data. The RF section converts an inbound RF voice signal into the inbound voice symbol stream, converts the outbound voice symbol stream into an outbound RF voice signal, converts an inbound RF data signal into the inbound data symbol stream, and converts the outbound data symbol stream into an outbound RF data signal. The interface module provides coupling between the baseband processing module, the RF section, and with off-chip circuits.

    摘要： An RFIC includes first and second RF sections, first and second PHY processing modules, first and second upper layer processing modules, and memory. When the RFIC is in a first receive mode, the first RF section, the first PHY processing module, and the first upper layers processing module convert a first inbound RF signal into a first inbound audio signal in accordance with a first wireless communication protocol. When the RFIC is in a second receive mode, the second RF section, the second PHY processing module, and the second upper layers processing module convert a second inbound RF signal into a second inbound audio signal in accordance with a second wireless communication protocol. The memory stores the first and second inbound audio signals. The first PHY processing module retrieves, based on the receive mode, the first or second inbound audio signal from the memory and converts the first or second inbound audio signal into a first or second inbound analog audio signal.
