TIDEP-01012: Sensors forum

Part Number: TIDEP-01012
Other Parts Discussed in Thread: AWR1243

Dear TI-Team,

we are testing the TIDEP-01012 successfully. However, we are currently checking the legal requirements and are wondering what is the transmitted power of the antennas? I could not find any information in the documentation or mmWaveStudio regarding the transmitting antennas. Can it be controlled or read out somewhere?

As far as I understood the RF-module takes max. 8A with 5V which should be equal to 40W. This would result to P(dBm) = 10 * log10( 1000 * P(W) ) = 46 dBm

Could you confirm that?

Best,

Andreas

  • Hi,

    We are checking with our systems team and will get back to you later this week

    Thank you

  • Hi Andreas, 

    First: I recommend consulting with your local radio licensing authority for maximum power levels and testing requirements in your territory. 

    The AWR datasheets describe the maximum output power per TX. The DFP ICD describes the attenuation functionality.

    AWR1243 shows a 12dBm typical output power per TX. Each antenna is about 10dBi from 76GHz to 81GHz (some drop from that), see the http://www.ti.com/tool/MMWCAS-RF-EVM user guide. Losses on the GCPW lines from each TX to the antenna are about 2dB. 

    So max EIRP = Pt - Loss + Gain = 12 - 2 + 10 = 20dBm per active TX.

    That can be brought down using the TX attenuators. 

    We have an application note that describes some of the regulatory requirements here: http://www.ti.com/lit/an/spracp3/spracp3.pdf

    Thank you,
