The low-power receiver consumes 267 mu W and provides a single communication channel at 100 kb/s in the 4-GHz band, with a -57-dBm sensitivity. The second receiver provides a better performance and takes full advantage of the FM-UWB features, as it implements wireless communication with up to four parallel channels sharing the same RF band.
