Junction temperature for HMC608

Dear Sir/Madam,

I wonder knowing the junction temperature of HMC608. The datasheet only shows storage temperature and channel temperture.


  • Hi,

    In general `junction` term is used for HBTs and `channel `term is used for FETs. For HMC datasheets, you can assume channel is same with the junction temperature. Since HMC608 is a pHemt device, `channel temperature` term is used.

    If you would like to go with `junction` term, then you can take max junction temperature as 175 C.
