high power mixer?

[CopperCone]

Can you mix high power signals? Like if you had two high power signals you want to efficiently mix without amplification afterwords.

It is possible for microwaves.

Nonlinear mix, not linear superposition (audio mixing).

Here's an example at power: http://davidberning.com/technology

Only used as a DC transformer, but that's one possible application of a mixer: synchronous modulating and demodulating at a driven clock frequency.

I don't know of any general method for high frequencies.  At low frequencies, it's just ordinary power electronics.

Do you want a "transmit" mixer ?

What frequency range should it have ?
What are the power levels ?
Is efficiency an issue ?
