9.3.1.2 Transmit Subsystem

The AWR2243 transmit subsystem consists of three parallel transmit chains, each with independent phase and amplitude control. All three transmitters can be used simultaneously or in time-multiplexed fashion. The device supports binary phase modulation for MIMO radar and interference mitigation. For AWR2243, 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 13 dBm at the antenna port on the PCB. The transmit chains also support programmable backoff for system optimization.

Figure 9-2 describes the transmit subsystem.
