• RE: HMC561LP3 Possible Failure?

    Hi,

    It sounds like the internal MIM cap on the output may be damaged. 

    These devices are very sensitive to ESD; since ESD isn't listed on the datasheet I suspect it is Class 0. 

    Best regards,

  • RE: HMC561LP3 VGG current

    Hi there, 

    I was unable to find any measured data on the gate current, it's very low though a few mA's at most. The bias needs to be turned on in a particular order, gate voltage first to pinch off the current, then the drain, then adjust the gate voltage…
