• stepped attenuator in RF chain justification

    hello

    I am designing the RF part of the transmitter chain shown in the figure below. The signal level measured from the modulator's output ranges of -30 dBm. This design aims to amplify this signal and deliver variable power in the range of 37-40 dBm…

  • HMC451LP3/HMC451LC3/HMC441LC3B_2nd harmonic level

    Dear team,

    We are reviewing the devices for the test and measurement application.

    Coule we know the 2nd harmonic level about the following devices?

    1. HMC451LP3

    2. HMC451LC3

    3. HMC441LC3B

    We are looking forward to your advice.

    Thank you

    Regards,

  • RE: HMC441 and HMC451 suggested layouts solder mask

    Hi kris565,

    For the HMC441LC3B I see that solder-mask does not appear between Vdd and the adjacent NC pins (see the grey rectangles below, which overlap the device pads...at right, side-by-side with the Functional Diagram):

    .

    Those NC pins (as defined…

  • 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.
