When i simulated the gilbert mixer to get the IIP3 with spectreRF.
I used the QPSS & QPAC to try to get the IIP3.
I setted Sweep Range: -70 dBm-> 10dBm
Sweep type: Linear and No of the Steps = 15
But the software always didn't finish the simulation.
it stopped at the 11th point.
So i couldn't get the IIP3.
Is anyone know how to solve this simulation problem?
