In the AWR2243 single-chip calibration document ( Self-Calibration in TI’s mmWave Radar Devices ), the third calibration item is LO Distribution Calibration . It is mentioned in the document that a set of buffers distributes the LO signal to the transmit and receive paths respectively. I suspect the buffers are located within the red block shown in the figure below. The document mentions that LO Distribution Calibration is implemented by combining closed-loop calibration using on-chip power detectors to suppress process variations and lookup table compensation for temperature drift. I would like to confirm whether the on-chip power detectors refer to the block marked with the red box in the attached figure. If this is the case, the LO routed to the TX path can be calibrated via the PD. However, how is the LO distributed to the RX path calibrated? If not, I fail to understand the underlying principle of closed-loop calibration using on-chip power detectors to suppress process variations. Your advice would be highly appreciated.数据通信模块AWR2243https://e2echina.ti.com/support/sensors/f/sensors-forum/1095524/ldc1614-ldc1614/3943207Wed, 23 Sep 2026 08:59:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:c02d6cd6-15b1-44d3-af93-236c06dfb9aeshuo guo可以尝试，但是光耦隔离的话占用体积还是比较大的，PCB也就是20*20cm，正面不能部件，只能走B面，30多个线圈，恐怕摆不下https://e2echina.ti.com/support/sensors/f/sensors-forum/1095524/ldc1614-ldc1614/3943202Wed, 23 Sep 2026 06:37:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:122c172d-8011-4eb5-9267-66a28bd4bc36Vivian Gao光耦这类的隔离芯片试试呢
