Hi, I have a doubt, the classic connection of the mixer is as shown in figure:
I know C3 = 100nF impedence ~0 ohm
In the datasheet there is write the impedence of single pin input (1 and 2) is 4700 ohm.
I have a impedence in input is 50 ohm.
My question is: If the pin 2 with impedence is 4700 ohm is to ~ground at 10.7Mhz I see only the impedance of pin 1 (4700 ohm)? or else I see the impedece of pin 1 + pin 2 = 4700 + 4700 = 9400 ohm ??
