Your comments are really helpfull. I am aware of PIN switching, but I can't use it because it requires a relatively high current (~mA) while the power consumption of the backscattering system must be as low as possible (< 1 mA). This is the reason why I've been thinking of the dual gate mosfet...
Hi all,
I am currently trying to perform backscattering modulation for an RF link operating at the UHF band. The data rate that I intend to use is low (audio signals). Could I use a dual gate mosfet as a shunt switch at the terminals of the backscatterer antenna? Do I have to control both gates...
