PRODUCTION DATA.
Refer to the PDF data sheet for device specific package drawings
The AWR1243 transmit subsystem consists of three parallel transmit chains, each with independent phase and amplitude control. A maximum of two transmit chains can be operational at the same time (while all three can be used simultaneously for AWR1243P). However all three chains can be operated together in a time-multiplexed fashion. The device supports binary phase modulation for MIMO radar and interference mitigation. For AWR1243P, 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.
