mmWave connecting to separate antenna

IWR6843: Antenna design

Lorenzo Nava73
Prodigy 230 points
Part Number: IWR6843

For our applications we are considering our antenna design, so we need to better understand the following information:

  • Maximum input power of the receivers
  • Input 1dB compression point of the receivers
  • Input IP3
  • Data about the spurious emission and harmonics of the transmitters
  • Matching of the transmitters (S11)
  • Matching of the receivers (S11)
  • Isolation between the TXs and all the RXs
  • Isolation between adjacent receivers and isolation between other receivers (not including the adjacent one) 

Moreover we would like to get these other details

  • Gain and phase mismatch between the receivers

Thanks

    Hello, 

        Please find the below information. 

    • Matching of the transmitters (S11) : <-10dB
    • Matching of the receivers (S11): < -10dB
    • Isolation between the TXs and all the RXs : Isolation between adjacent receivers and isolation between other receivers (not including the adjacent one) :RX-RX/TX-TX isolation is typically better than 35dB.
    • Input 1dB compression point of the receivers: Target is :-13 -14dBm. 
    • Gain/Phase mismatches and other RF parameters are undergoing through the test/measurements. 

    Thanks and regards,

    Hello,

    thank you.

    Please can you send me the gain/phase mismatches as soon as you have it?

    Thank you and regards.

    Hello,

         The test process for these parameters is ongoing and we do not have a projected date for completion and release.  Please sign up for updates by clicking the Alert me function on the Product Folder page.  By activating this feature, you will be notified when the datasheet has been updated. 

    Thanks and regards,
