I’m looking to implement an amplifier in the range of 100KHz to 2MHz to obtain amplitude and phase information.
I followed the design in circuit diagram 9a Gain-of-One balanced modulator. Pin 3-6 and the capacitors with powers are not connected.
Signals input to modulation input and carrier input are same, which is the yellow signal in the picture below. And the blue line is the result. It is very different from the result of simulation (the red signal).
Why the results are so inconsistent? What I have missed?
