RECEIVER CONFIGURABLE IN A PLURALITY OF MODES

摘要

Methods and corresponding systems for receiving a radio frequency signal include a receiver capable of switching operating modes and operable to receive the radio frequency signal in any of the operating modes. A metric monitor is coupled to the receiver and operable to provide a metric. A controller is responsive to the metric and operable to switch the receiver between the operating modes. The operating modes can include a zero intermediate frequency (ZIF) mode and a very low intermediate frequency (VLIF) mode. The metric can include a received signal strength indicator (RSSI) and an adjacent channel indicator. The receiver can be configured to operate in the ZIF mode in response to the RSSI value satisfying a threshold and configured to operate in the VLIF mode in response to the RSSI value failing to satisfy the threshold.
