Title: IP3 using pss/qpss (shooting and flexible balance)
Post by mindy on Jul 27^th, 2007, 3:58pm

Hi,
I used PSS shooting to simulate IP3(mixer) at given input level, IM3=-70dB
I also use PSS flexible balance to simulate IP3 at the same given input level, with oversample factor =4, I got IM3=-80dB.
I tried to use QPSS flexible balance to verity the IP3, I found out there is no oversample factor. I got the same IM3=-70dB

What is the best way to get the accurate IP3? what is the right number for oversample factor?
Thanks
mindy :)

Hi.

Try to plot both Pout and Pim3.
Check wheter Pim3 curve is gradient of 3dB/dB.
