Hi,
Is there anyway to do manual analysis of, say a quadrature hybrid to determine its bandwidth (as I was able to do in low frequency cmos circuits)?
While discussing quadrature hybrid, Pozar writes " ... the bandwidth of a branch-line hybrid can be increased to a decade or more by using mutiple sections in cascade". Any analytical way to show if this statement is correct?
I have also noticed that (similar to what happens in a constant GBP opamp) if I increase the bandwidth, the value of S11 gets affected. Why this
happens ?
