Solution

a) J. H. Tsai, P. S. Wu, C. S. Lin, T. W. Huang, J. G. J. Chern and W. C. Huang, \"A 25–75 GHz Broadband Gilbert-Cell Mixer Using 90-nm CMOS Technology,\" in IEEE Microwave and Wireless Components Letters, vol. 17, no. 4, pp. 247-249, April 2007.

Idea:- A compact and broadband 25-75-GHz fully integrated double-balance Gilbert-cell mixer is developed. A broadband matching network, LC ladder, for Gilbert-cell mixer transconductance stage design is introduced to achieve the flatness of conversion gain and good RF port impedance match over broad bandwidth.
