摘要： A single receiver is operable to utilize full spectrum capture to capture signals over a wide spectrum comprising a plurality of WiFi frequency bands, extract one or more WiFi channels from said captured signals and aggregate a plurality of blocks of said WiFi channels to create one or more aggregated WiFi channels. The WiFi frequency bands include 2.4 GHz and 5 GHz WiFi frequency bands. A plurality of blocks of the WiFi channels may be aggregated from contiguous blocks of spectrum and/or non-contiguous blocks of spectrum in one or more of said plurality of WiFi frequency bands. One or more non-WiFi channels may be filtered out from the captured signals. One or more aggregated WiFi channels may be assigned to one or more WiFi enabled communication devices. At least a portion of the one or more aggregated WiFi channels may be dynamically assigned to one or more other WiFi enabled communication devices.

摘要： Receiver architectures and methods of processing harmonic rich input signals employing harmonic suppression mixers are disclosed herein. The disclosed receivers, mixers, and methods enable a receiver to achieve the advantages of switching mixers while greatly reducing the mixer response to the undesired harmonics. A harmonic mixer can include a plurality of mixers coupled to an input signal. A plurality of phases of a local oscillator signal can be generated from a single local oscillator output. Each of the phases can be used to drive an input of one of the mixers. The mixer outputs can be combined to generate a frequency converted output that has harmonic rejection.

摘要： A receiver can be configured to include an RF front end that is configured to downconvert a received signal to a baseband signal or a low Intermediate Frequency (IF) signal. The receiver can downconvert the desired signal from an RF frequency in the presence of numerous interference sources to a baseband or low IF signal for filtering and channel selection. The filtered baseband or low IF signal can be converted to a digital representation. The digital representation of the signal can be upconverted in the digital domain to a programmable IF frequency. The digital IF signal can be converted to an analog IF signal that can be processed by legacy hardware.

摘要： A receiver (100) configured to selectively receive an RF signal from an operating band having a plurality of RF channels. The receiver (100) is configured to upconvert (200) the desired RF channel to an intermediate frequency (IF) greater than the RF channel frequencies. The upconverted RF channel is downconverted (230) to baseband or a low IF. The receiver can perform channel selection by filtering (242, 244) the baseband or low IF signal. The baseband or low IF signal can be upconverted to (240) a programmable output IF.
