SWRS222B December 2018 – April 2020 AWR1843
Refer to the PDF data sheet for device specific package drawings
The AWR1843 transmit subsystem consists of three parallel transmit chains, each with independent phase and amplitude control. All three transmitters can be used simultaneously. For AWR1843, additional phase shifters are associated with Tx channels, and these can programmed on a per chirp basis.
Each transmit chain can deliver a maximum of 12 dBm at the antenna port on the PCB. The transmit chains also support programmable backoff for system optimization.
Figure 6-3 describes the transmit subsystem.
