Hello,

I am looking for a CM LNA, which is described in this paper:

https://pdfs.semanticscholar.org/bdda/862ff38de85544354baed2c254f705dc0bc7.pdf

It multiplies an analog signal at high frequency (6-10 GHz) to -1 or 1. I image that the supply voltage is not the DC, but we can change it at frequency of some MHz, which then multiplies the input signal to -1 or 1.

If you have any information about this kind of CM LNA, commercial product or academic product, please let's me know.

Thanks !
Tu
