Stingray X/Ku Phased Array reference schematic questions

Category: Hardware
Product Number: ADAR1000EVAL1Z


For preparing the new prj, I'm researching Sting Array Schematic and BOM (059522a revision).

Then I just found some parts in schematic file but it's not included in BOM.

Please help to share it in the detail. (what's component? How it work?...)

- Schematic page 12: Reguators Part

- Schematic page 13: Positive/Negative Part

Added Stingray tag. Updated Product Number. Corrected subject typo

  • Hello, 

    The DC regulator components are indeed on the BOM and the schematic. The schematic details the circuitry for all the DC rails, which are derived from an external +12 VDC supply via the P1/P2 connector. Links to the parts can be found on the wiki page.

    BOM Item # Part # Description Schematic Sheet
    89 ADP5074 +12V to -6.0V DC-DC Inverting Regulator 15
    90 LT8642 +12V to +3.3V Step Down Switcher 16
    91 LT8652 +12V to +5.0V Step Down Switcher 16
    92 LT3093 -6.0V to -3.3V Negative Linear Regulator 17
    93 LT3094 -6.0V to -3.3V Negative Linear Regulator 17
    108 LT8606 +3.3V Step Down Regulator 15
    109 ADP150 +1.8V Linear Regulator 15


  • Hi,

    I got your point. Thanks for your explanation.

    Moreover, how DC rail can be showed on PCB layout?

    Thks & BRs,
