    摘要： A down conversion module includes a mixer operable to down convert an amplified receive signal from a low noise amplifier, based on a local oscillation, to produce a mixer output signal. A mixer load section is operable to produce a down converted signal from mixer output at an output of the mixer load section. A direct current (DC) offset cancellation module is operable to measure a DC offset at the output of the mixer load section, to generate cancellation currents and to combine the cancellation currents with the mixer output signal to provide DC offset cancellation.

    摘要： Methods and apparatus are disclosed to simultaneously, wirelessly test semiconductor components formed on a semiconductor wafer. The semiconductor components transmit respective outcomes of a self-contained testing operation to wireless automatic test equipment via a common communication channel. Multiple receiving antennas observe the outcomes from multiple directions in three dimensional space. The wireless automatic test equipment determines whether one or more of the semiconductor components operate as expected and, optionally, may use properties of the three dimensional space to determine a location of one or more of the semiconductor components. The wireless testing equipment may additionally determine performance of the semiconductor components by detecting infrared energy emitted, transmitted, and/or reflected by the semiconductor wafer before, during, and/or after a self-contained testing operation.

    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.
