• Questions about HMC1121

    Hello,
     I am working in a design and looking for a PA with 5.1 - 5.9 GHZ  frequency range .
    The HMC1121 PA looks great but I have several questions about this part:1.- Frequency range is 5.5 - 8.5 GHZ but  plots on page 8 show the behaviour from…
  • HMC1121 Evaluation Board

    What is the order of mounting the board: first, the electrical radio elements are mounted on the board, and then the mounted board is attached to the base, or vice versa, first the empty board is attached to the base, and then the elements are mounted…
  • -URGENT- HMC1121 recommended bias current

    Hi

    Regarding datasheet, VGG1-4 are gate Controls for the Amplifier. Adjust VGG1 through VGG4 to achieve the recommended bias current. However I don't see the recommended value.

    Could you please give me the recommended and the max value ? The custom…

  • Recommended Active Bias Controller for HMC1121

    Is there a recommended active bias controller similar to the HMC980 available for the HMC1121 that can handle the 2200mA drain current?

  • Allowable output mismatch for the HMC1121

    Hi,

    I'm considering using the HMC1121 to drive an antenna and trying to determine whether I'll need an isolator between the amplifier and the antenna. Are there any specs on the impedance mismatch / VSWR that is permissible on the output of this part…

  • Turn on/off sequence for HMC7357

    Hello,

    I want to use HMC7357 for a new design. I do not see on datasheet any info about turn on/off sequence for this device. On others amplifiers, it is described on datasheet the need of this sequence (for instance: HMC1121). Does this part need a…
