Hello,

We are using two CC1310 module for our application on same design at same frequency band.

while designing pcb design for same, is there any restriction of distance between two CC1310 module,

As there are two antenna coming on same PCB, how the placement of two antenna required ?

Can we place the two module on opposite layer of PCB ?

What are the issue can face for design ? if there any range issue ?

Hi,

Will the two CC1310 be operating at exactly the same time ?

Will there be a delta in the frequency, if they are operating in the same frequency band ?

Regards,

Richard

Hi,

Have you considered the co-channel rejection since you will be operating at the same time and same frequency?

Both radios can operate in the same frequency band but this is not the same at operating at the same frequency.

If operating at the same time, then for your range calculations this must be taken into account since the range will be reduced due to practical sensitivity limit will be dominated by the co-channel or adjacent channel / selectivity rejection. This will dominate the link budget far more than the PCB design.

Richard

Hello,

Thank you for reply.

let me know, how much distance between the two cc1310 module we can placed,

so there will be no reduction in range.

Hello,

In another scenario, if suppose we have 2 devices connected to two different instrument,

what minimum distance between two devices should maintain to avoid crosstalk & to get

proper link budget.

You have to calculate this from the co-channel blocking numbers.

Generally, if you have 2 TX devices close to each other you typically should ensure that only one of them is on at a given time and/ or that they have sufficient frequency offset from each other, see the blocking numbers in the datasheet.
