Part Number: IWR1443
Since there is a phase shifter in each transmitting channel, I want to steer the direction of beam by changing the phase of each channel. However, I cannot find the corresponding API. Can you tell me where can I find it?
Another question, based on the MMW demo, TI does the frequency domain beamforming for the received data without transmitting beamforming. Since there is a phase shifter for each channel, why the demo conducts the receiving beamforming instead of tranmistting beamforming? Are there any considerations?
And also, where is the Technical Reference Manual for each of xWR14/16 chips? What I can find is just the datasheet.
It is about the time to graduate.
In reply to Vaibhav Mahimkar:
Thanks for replying.
In the IWR1443 datasheet it says that "The IWR1443 transmit subsystem consists of three parallel transmit chains, each with independent phase and amplitude control. " Also, as the picture showing below, is the function cycled in blue phase shifter?

In reply to Francois Charlot:
The AWR1243 device has Tx phase shifter, and Binary Phase Modulation. The other devices AWR1642, IWR1642, AWR1443, IWR1443 all contain Binary Phase Modulation. The text is being clarified in the next device datasheets.
The BPM and linear phase shifter are in a generic phase shift (delay block).
