BJT MIXER QUESTION: should it be used as non-llinear mode or switching mode?
 

very simple application..i have two input frequencies and would like to
use single-fed bjt transistor to get a difference frequency...
any other design recommendation is highly appreciated......thanks!

A balanced switching mixer using two BJTs would be a lot better. Or,
you could use bus switches as in the FST3125 which would be better
still.

Just make sure one signal is large enough to drive the device well into it's
non-linear region.

can you give me a simple configuration?or schematic?
thanks!

using fixed bias, i will connect each frequency input to the bjt's base
which is emitter couple then how will i combine them?
