Abstract
A multi-band wireless transceiver having a plurality of signal-processing paths, and further having a function of making wireless communication through a plurality of frequency bands by selecting one of the signal-processing paths, includes a band identification circuit for identifying a frequency band, the band identification circuit identifying a frequency band in dependence on a frequency-band information received from a controller which controls an operation of the multi-band wireless transceiver, and selecting one of the signal-processing paths in accordance with the identified frequency band.
Claims25
A multi-band wireless transceiver having a plurality of signal-processing paths, and further having a function of making wireless communication through a plurality of frequency bands by selecting one of said signal-processing paths,
- said multi-band wireless transceiver comprising a band identification circuit for identifying a frequency band, said band identification circuit identifying a frequency band in dependence on a frequency-band information received from a controller which controls an operation of said multi-band wireless transceiver, and selecting one of said signal-processing paths in accordance with the identified frequency band.
A method of controlling a multi-band wireless transceiver having a plurality of signal-processing paths, and further having a function of making wireless communication through a plurality of frequency bands by selecting one of said signal-processing paths, comprising the steps of:
