6.3.1.2 Transmit Subsystem

The IWR1642 transmit subsystem consists of two parallel transmit chains, each with independent phase and amplitude control. The device supports binary phase modulation for MIMO radar and interference mitigation.

Each transmit chain can deliver a maximum of 12.5 dBm at the antenna port on the PCB. The transmit chains also support programmable backoff for system optimization.

Figure 6-2 describes the transmit subsystem.
