The reason that I ask is because I have a Bruhan's VLF converter that uses, what he called, a ring mixer. The Burhan's converter has a MC4066 analog switch where the control inputs of two fet switches are inverted and the other two are non inverted. When I saw the schematic of the H mode mixer, it reminded me of the Burhan's VLF converter. The difference is the transformers that Burhans used. They were audio transformers that covered the VLF range.
