  • Wireless telecommunications multi-carrier receiver architecture
    Patent number: 6813320
    Abstract: A receiver (10) for a wireless telecommunications system that provides relatively wideband signal processing of received signals without increased signal distortion so that multiple received signals can be simultaneously processed. The receiver (10) includes a specialized LNA (16), frequency down-converter (18) and ADC (20) to perform the wideband signal processing while maintaining receiver performance. The frequency down-converter (18) employs a suitable mixer (28), BPA (32), attenuator (34), and transformer (36) that are tuned to provide the desired frequency down-conversion and amplitude control over the desired wideband. The down-converter devices are selected depending on the particular performance criteria of the ADC (20). A specialized digital channelizer (22) is included in the receiver (10) that receives the digital signal from the ADC (20), and separates the signals into the multiple channels.

The receiver (10) includes a specialized LNA (16), frequency down-converter (18) and ADC (20) to perform the wideband signal processing while maintaining receiver performance. A specialized digital channelizer (22) is included in the receiver (10) that receives the digital signal from the ADC (20), and separates the signals into the multiple channels. In one embodiment, the frequency down-conversion is performed in a single down-conversion process, and the ADC (20) employs delta-sigma processing to provide digital conversion over the complete frequency band.

  • Multi-carrier receiver frequency conversion architecture
    Patent number: 6741847
    Abstract: A frequency down-converter (18) for a receiver (10) in a wireless telecommunications system. The down-converter (18) is capable of simultaneously processing a plurality of signal channels without increased signal distortion over a relatively wide bandwidth. The frequency down-converter (18) employs a suitable mixer (28), bandpass filter (32), attenuator (34) and transformer (36) that are tuned to provide the desired frequency down-conversion and amplitude control over the desired wideband width. In one embodiment, the bandpass filter passes a frequency band at 25 MHz or above. The frequency down-converter (18) generates the IF signal in a single step down-conversion process, or generates the IF signal and then a baseband signal in a two step down-conversion process.
