HMC812 Eval kit information


Please help to share the user guide or schematic information of the HMC812 Evaluation board.

part no. 123768-HMC812LC4 Evaluation Board - HMC812LC4 Evaluation PCB.

Also please help to share best suited DAC to interface with HMC812 for controlling attenuation.



Hi Sai,

Attached is the PCB layout and gerber files for the HMC812LC4 Evaluation Board. This is a simple EVB circuit, we do not have the user guide or schematic diagram. The layout follows the same application circuit as shown in the HMC812LC4 datasheet.


Take a look at AD5429/AD5439/AD5449 DAC. With the reference circuit below copied from the datasheet, it would drive the HMC812LC4's two control input voltages ranging from -3V to 0V.



  • HI S.ilke,

    Thanks for your prompt reply.

    I was thinking of using AD5721/61 DAC Device. Whether that is suitable or not. Please confirm accordingly.
