Mode A: High sensitivity mode; Mode B: High Linearity mode. As defined in Paragraph 4.1.1.
An intermediate bandwidth of 300 kHz can also be selected by using additional settings described in section 5.2.8.
Throughout this document, digital signal levels are named “high” or “1”, and “low” or “0”.
SPR strongly depends on the design of the application board and the choice of the external components.
Values down to -70 dBm can be achieved with careful design.
