Hi Team,
- If we pass 2.4GHz RF signals (RF_P & RF_N) through a ribbon cable (either standard connector or custom Flexi cable) to another PCB. Is it acceptable and what are losses and noise.

Hi Team,
Hi Ranjani,
I assume these are the type of ribbon cable you are referring to?
If so. then can't be used for the RF path as it is not designed to propagate RF signals. As for losses and noise, expect to see high loss (no signal) and only noise as ribbon cables are typically not matched to 50 ohms.
If you are looking for flexibility perhaps consider a U.FL connector and cable.
Best regards,

Could you provide the part number of the flexi cable? We can tell quickly whether it is ok to use.

Planning to design our own based on signals required between two Rigid PCB's. It is recommendable to send RF single ended signal with 50E impedance control via Flexi cable? Anyone designed like this. Is it safe for Regulatory testing FCC.
It is possible but we would not recommend a custom RF cable as it tends to be expensive and time consuming. We did have experimental design come through that had a flexible RF path but it started to behave more like an antenna as it was too long (several wavelengths at 2.4GHz) and lacked proper shielding.
