8.3.1.2 Transmit Subsystem

The IWR6843 transmit subsystem consists of three parallel transmit chains, each with independent phase and amplitude control. The device supports 6-bit linear phase modulation for MIMO radar, Tx Beam forming applications, and interference mitigation.

The transmit chains also support programmable backoff for system optimization.

Figure 8-3 describes the transmit subsystem.
