dual gate mosfet mixer

Hello

I am looking for theses, references, papers on dual gate mixers for fets, mesfets or phemts preferable.

thanks

The attached zip-file contains
1. A 3-V RF-CMOS dual-gate up-conversion mixer.pdf
2. A comprehensive design method for dual-gate MOSFET mixers.pdf
3. dualfet1.pdf
4. dualfet2.pdf
5. intermodulation analysis of dual-gate FET mixers.pdf
6. dual gate MESFET mixer.pdf

I hope this archives are helpful to you.

BR.

Very good！

Thank for the papers.
