7.3.1.2 Transmit Subsystem

The device transmit subsystem consists of four parallel transmit chains, each with independent phase and amplitude control. All four transmitters can be used simultaneously or in time-multiplexed fashion. The device supports binary phase modulation and a 6 bit programmable phase shifter for beamforming control on a per chirp basis for each channel as indicated in the figure below.

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 7-3 describes the transmit subsystem.
