Customer plan to design HMC1048ALC3B to use it in X-Band Down-converter.
Is it able to work if RF input power level is lower than -80dBm, even -100dBm?
If you have any document dynamic range, could you provide it for us?
The HMC1048A has not been released yet and won't be released till Q1 2018.
I tested this with the HMC1048 mixer and the mixer downconverts for X Band RF signals at -100dBm. Even so, I do advise to use an RF LNA in your receiver before directly downconverting.
