• HMC985ALP4KE_DC blocking capacitor of RF In/Out port

    Dear Team,

    I think that HMC985ALP4KE needs DC blocking capacitors at the RF In/Out port.

    But I can't the DC blocking capactor value(refer to the EVAL-CN0390-Schematic-revB.pdf).

    I want to get the your advice.


    Best regards,

    This part is EAR99. The attached RFIC selection guide lists the ECCN codes for all of ADI's RF products.

    You need a PLL which drives a frequency doubler which drives an amplifier. Possible choices might be ADF4371 (PLL),  HMC1105 (frequency doubler) and HMC7229 (amplifier). These are not the only choices.
