Hello,
I have a chip that has 2.0" I2C traces leading from the microcontroller up to it (3.4Mhz max). Will this interfere with the 2.4Ghz transceiver that is also on the same PCB?

I looked up the wavelength for 2.4Ghz and it is 0.125 meters (4.9"), but I am not able to determine if this is a problem. If this is a problem, what can I do to correct it? (I cannot shorten the I2C lines, they have to be in this specific location).

Thanks and any help is greatly appreciated!

 

I think you want to consider the wavelength of the I2C signal that is on the traces in question. Not the wavelength of a signal on another trace.

I am not following? I thought thats what I was doing?

 

You looked up the wavelength for 2.4GHz, but I2C doesn't transmit at that frequency. If you're going to use I2C at 3.4MHz, use the wavelength for that. But I'm not experienced with circuits at those frequencies, so hopefully someone else will chime in.
