Hello,
I was examining the following schematic taken from the SA605 datasheet.
Whats the benefit of the circled group of components?
Why is the second input to the mixer not simply AC coupled to ground and the input signal fed to the first input on the mixer?
I simulated the circled components expecting to see a 180 degree phase shift across pins 1 and 2 but instead I found that the two pins are in phase and one is simply of smaller magnitude than the other. Pointless
