Helo every body,
I am a beginner in RF design. I have designed a CMOS LNA at 2.4GHz and i have finished the layout. Unfortunately, i did not have access to an electromagnetic simulation tool and i must make the necessary precautions to prevent the magnetic coupling between inductances between them, and each inductor with other interconnects.
So is there a method to avoid these couplings that can degrade the performances of the LNA after the fabriation. Or is there a design rule (rule of thumb) that i can follow to avoid this coupling.
Thanks a lot
Best Regards

Hello.
Just a rough estimation - distance between inductors should be at least 50 - 100 um.
