TV Design Considerations Using High-Gain Dual-Gate Mosfets

A 1.9 GHz double balanced dual gate downconversion mixer in 0.8 μm CMOS

“…The dual gate FET mixers in both MESFET and MOSFET variety are well known techniques [2,3] for realizing conversion gain and reasonable noise figure similar to single gate mixers but with the added advantage of isolated signal and local oscillator ports. This allows separate matching and inherent LO-RF isolation without external filtering.…”
