Hi Peter,
Thanks for the response.
I am not quite sure I understand how the balun affects the quadrature phase balance performance. The balun is just used to take the single ended RF input and make it differential, correct? But the actual 90 degree phase splitting is inside the demodulator device, no? So shouldn't balance be a demodulator spec, rather than the balun?
Also, I looked at the balance plot on the balun and I am not sure I understand the plot. I see a line that runs straight across the 180 degree mark and another line that straight across the 0 degree mark. How did you interpret the plot?
Regards,
Stan
