Question

Hi,

We are planning to use SR4C033-R in our design. The antenna will be placed on the right edge of the PCB with the suggested clearance. On the left edge we have an RGB led for indication. Can we have an LED to the left side of the antenna?

Regards

Ashok

Hi Ashok,

It is ok to place the LEDs to the left of the antenna as long as they are at least 15mm away from the antenna.  We also suggest that the traces that feed the LEDs be placed on the inner layers of the board to isolate them from radiating noise that could be picked up by the antenna.
Best regards,
