SWRS211C May 2017 – October 2018 IWR1443
The IWR1443 transmit subsystem consists of three parallel transmit chains, each with independent phase and amplitude control. A maximum of 2 transmit chains can be operational at the same time. However all 3 chains can be operated together in a time multiplexed fashion.The device supports binary phase modulation for MIMO radar and interference mitigation.
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.
