BTS-WiMAX / WiBro Transceiver
Analog Devices’ WiMAX solutions are based on a direct up conversion Tx path for low part count, less spurs, less filtering and lower power consumption. The Rx path is either an IF sampling or Superhet baseband I-Q sampling architecture. These are quite appropriate for flexible implementations and can easily be upgraded for higher RF frequency operation. Both Rx signal chains are specifically designed for high sensitivity and linearity, and inherently offer very good selectivity.
