摘要： A design of integrated circuit components to prevent accidental turn on when large input signals are accepted. With integrated circuits operated at lower power supply voltages, input signals having large peak values can tend to turn on devices within the integrated circuit erroneously. By placing amplifiers within the integrated circuits where input signals are received and removing the power of such amplifiers, accidental turn on can be minimized.

摘要： The present invention provides adjusting of a radio frequency (RF) receiver that includes processing that begins by enabling an initial setting of the RF receiver, wherein the initial setting is based on a bandwidth of a channel of a plurality of channels. The processing continues by receiving an RF signal containing a preamble of a frame via one of the plurality of channels. The processing continues by converting the RF signal to a baseband signal based on the initial setting. The processing continues by determining channel type of the one of the plurality of channels based on the baseband signal. The processing continues by determining whether the channel type corresponds to the bandwidth of the initial setting. The processing continues by, when the channel type does not correspond to the bandwidth of the initial setting, adjusting setting of the RF receiver based on the channel type.

摘要： A transceiver includes a receiver section and a transmitter section. The receiver section converts an inbound Multiple Frequency Bands Multiple Standards (MFBMS) signal into a down converted signal, wherein the inbound MFBMS signal includes a desired signal component and an undesired signal component. In addition, the receiver section determines spectral positioning of the undesired signal component with respect to the desired signal component and adjusts at least one of the MFBMS signal and the down converted signal based on the spectral positioning to substantially reduce adverse affects of the undesired signal component on the desired signal component to produce an adjusted signal. The transmitter section converts an outbound symbol stream into an outbound MFBMS signal.

摘要： A wireless device includes an antenna, Radio Frequency (RF) circuitry, and baseband processing circuitry. The baseband processing circuitry couples to the RF circuitry and is operable to determine operational calibrations settings that may include pre-distortion characteristics and RF signal path settings, both of which are determined via calibration operations. The calibration operations are initiated when an operational value of the wireless device compares unfavorably to at least one operational threshold. Monitoring circuitry coupled to the RF circuitry and to the baseband processing circuitry monitors operational characteristics of the RF circuitry. Calibration operations may be initiated based upon RF circuitry temperature, supply voltage, PA current, PA gain input level/average, among other triggers.
