• HMC1121 Vgg

    Hi 

    What is the typical gate voltage 1-4 when Idd is 2200mA?

    Is the Gate voltage will varying with different batches of HMC1121 or different HMC1121 devices?

    If the gate voltage has variation on different HMC1121, than what is the voltage variation?

    Hi,

    What are the Idq limits for each stage assuming stages are biased separately?

    Thanks.

  • RE: HMC1121 Evaluation Board

    The HMC1121 has a metal heat spreader on its underside. When we are assembling the board, we start by adding all of the topside components and then attach the heat spreader. Doing it the other way around would be more difficult  because of the additional…

  • -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…

  • 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…
  • 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…

    Hi,

    I had a question for you about the article "Nonlinear Simulation of RF IC Amplifiers in Keysight Genesys and SystemVue".
    Please give me the file in Figure 8 if possible. (ADS software simulation file)

    Regards.

  • RE: 36GHz RF oscillation signal source

    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.
