two input for class E

[suribright]

Hi guy,
Is there any one know how to design two input for class E MOSFET ? Normally, class E turns on and turn off with one square-wave. I need to have two input at the same time: at 10 MHz and 16 MHz. Please help!

Do you want the output to be the product of the two inputs or the sum?

Good question @ crutschow. I want to have two outputs at two of that frequencies

You could give me sum or product, and separate them after.

It isn't what I can give you, it's what do you want? What is the purpose of this circuit?

No, the canonical class E amp can't handle more than one fundamental frequency, at least not without severely impacting efficiency and introducing lots of IMD. Running two separate class E amps and combining the output may be feasible, but isolating them would be difficult.

HI crutschow and mtwieg,
Here is the circuit I used for Class E **broken link removed** . I need to have to two inputs excitation (at 5 MHz and 6MHz) and some how we can separate them at load. Do you have any ideas? Thanks

HI crutschow and mtwieg, do you know how to solve above circuit? Thanks
