HMC641ALC4 vs ALP4 vs A-DIE frequency range ?

Hi all,

What is the lower input frequency limit @ HMC641ALC4 ?
In the datasheet, the specifications is covering DC to 20 GHz.

We think, this "DC" means the low frequency, equal 100MHz~.

Is it corect ?

Best regards,

    Hi sss,

    Unfortunately, the lower frequency on the older HMC datasheets were incorrectly specified.
    We are correcting this as we convert the datasheet to the ADI-format.

    We have converted the HMC641A-DIE and the -ALP4 datasheet already, and will convert the -ALC4 datasheet in the future. These can be operated from 100MHz.
