• EVAL-ADTR1107 Cal line S-Parameters

    Hello,
    
    Would it be possible to get Calibration Line S2P of the ADTR1107 ?
    especially as eval board doesn't come with RF connectors on the Calibration Path.
    
    I saw there is some documentation on the eval board datasheet.
    Would it be possible to get a…
  • ADTR1107 output harmonic level

    Do you have any graphs or data to show the relationship between the input level and the output harmonic level of the ADTR1107? I'm concerned about the 2nd harmonic level for radar applications.

    Best Regards,

  • ADAR1000+ADTR1107 proper TX to RX state bias switching sequence

    I'm working on a design using an ADAR1000 and ADTR1107. We need to switch between transmit and receive states every ~10ms or so. We plan to use the ADAR's TR pin to switch between transmit and receive states. Reading the documentation, I noticed that…

  • ADAR1000 + ADTR1107 evaluation setup failure, wrong pinout in UG-1283 Rev.A

    Hello,

    We're trying to evaluate the performance of ADAR1000 and ADTR1107 working together. We purchased one eval board for each chip. Our ADAR1000-EVALZ is a rev.D board.

    We downloaded all the available documentation for both boards, and proceeded…

  • I notice that you have a bias line between ADAR1000 and ADTR1107 that is dashed. Is that connection optional?

  • RE: ADAR1000 EVAL BORAD FOR RAPID RESEARCH PROTOTYIPNG

    a.  The eval boards were never cascaded in the linked video, they were in parallel.  Note that this was an early demonstration.  We do NOT recommend trying to build an array out of evaluation boards.  

    b.  It is not mandatory to use the ADTR1107.  The ADTR1107…

  • RE: Active bias controller

    I'm also working on system based on ADAR1000+QPM1002 in planar style for X-band and also intersted on your planar board design usin ADTR1107.

    Did you already finish your prototype work?

  • RE: ADAR1000 Gain Setting

    The oscillation seems to have less to do with gain and more with the attenuator being applied in the path. 

    • Does oscillation happen on all four Tx channels of the single ADAR1000?  i.e. across all four ADTR1107's?  
    • Have you tried changing the power…
  • RE: Q. ADAR1000-EVALZ vs ADAR1000-EVAL1Z

    The ADAR1000-EVALZ has a single ADAR1000 part in which to test.  The ADAR1000-EVAL1Z (Stingray) has 8 ADAR1000's and 32 ADTR1107 transmit/receive modules, and power circuitry to support the several supply rails and proper sequencing needed.  If you…
