Data Sheet - Detail ed Description
In differential mode peak is equal to VDD, in single ended mode peak is equal to VDD/2.
Note: It is important to note that the overall emitted power of the PA is mainly defined by the VDD and the impedance of the antenna itself.
The Rout of the PA gives only a minor change to the emitted power.
Figure 26. Power Amplifier
The following example demonstrates the calculation of impedance of the antenna and matching network (RANT+MATCH) for a specified output
power:
Conditions: VDD= 3V, Differential output mode, 10dBm is the desired output power.

8.10.6 RSSI
The AS3900 has an integrated received signal strength indication field (RSSI) that can be used by the Master to identify the signal strength to all
available Clients. If this block is turned on via the rssi_on bit in REG 0x20<3>, the actual signal strength can be read from REG 0x23<3:0>. The
rssi field provides a digital value for signal strength between 0µVrms and 150µVrms.
The rssi field is valid for the Client that communicates currently with the Master, which can be identified via the sid in REG 0x33<2:0>.
