• HMC637ALP5E Idd vs. Vgg1 && Power Up/Down Bias Sequence Problems

    Hello, 

    I have read many questions and answers about the HMC637ALP5E and various application documents.

    And there are three questions:

    1）The same type amplifier e.g. HMC797APM5E provides a relationship between Idd and Vgg1(Representative of a Typical D…

  • PHEMT bias sequencing circuit

    Hello.

    I'm system engineer, so don't know well about PHEMT or HEMT chip.

    I'd like to use HMC598 and HMC-ALH382, HMC-ALH476 like doubler or AMP.

    These chips are required some bias sequence.

    You can find PDF file about bias
