[W1GV] has a video that explains the design of a mixer with a dual gate MOSFET, that you can see below. The dual gate MOSFET is nearly ideal for this application with two separate gates that have ...

For example, the maximum gate voltage for a typical MOSFET is usually between 5 and 10V while IGBT ... before being fed to the photo-coupler, which feeds the L298 dual full bridge driver. The L298 can ...
