jr_dakota: On the simplicity idea, thats what attracted me to the phase shift transformer idea that Rick Campbell used and hence that idea was with sine waves for th LO. If there are no balanced mixer diodes involved as was discussed in another email then with tjust the purely transformer ideas I see pure sine waves having a home in that case.
I have an experiment I plan on a receiver I have that has 50 kHz as its last i.f. so here I see that I should be able to use a mere quadrature phase shift transformer without a mixer and just split the 50 kHz in two and let the transformer do its job of phase shifting. Now it is only an experiment. I will learn if I need a LO mixer signal to create sum and difference products in this case or not.
