Estimating Stingray(ADAR1000-EVAL1Z) power consumption

Hello,

I wonder the power consumption of Stingray for Tx state and Rx state

Thank you for your help.

  • Hi Jaemin, 

    In Tx state at nominal bias and all devices activated, the board is expected to consume approximately 55 W of DC power (12 V, 4.6 A). In Rx state at nominal bias and all devices activated, the board is expected to consume approximately 20 W of DC power (12 V, 1.6 A). Majority of the power consumption is due to the ADAR1000 (qty 8) and ADTR1107 (qty 32) ICs. Stingray (ADAR1000EVAL1Z) is powered from a single 12V rail with DC converters stepping down to the proper voltage rails for the various ICs. The converters/regulators have some inefficiencies which also contribute to the DC power consumption. A schematic can be found on the wiki if you want to see which components are used.
