CE compliance of nRF51822

[Vasco Tesi]

Hi, we are producing a BLE beacon using nRF51822 and at first we are interested only in CE qualification. Our design uses nRF51822-QFAA, build G0 (or GC or FA), with ST balun BALF-NRF01D3. The antenna is a meandered IFA printed on board. We strictly followed Nordic reference design, except for antenna (not comprised in the design) and balun/chip combination ( balun with QFAA is much more BOM and cost efficient). Does Nordic have any document with tests assessing compliance to regulatory standards requirements, with a configuration similar to our one? in document nWP-018, "Migrating to the latest nRF51822 chip version", our configuration seems not to be covered by a reference design (table 1, note 7) but i'm asking if there is any "last minute" update. Has anyone already performed any compliance test with a configuration equal or similar to our one? Thanks, bye

We haven't got any qualification on that specific same setup, but as long as you have followed the guidelines and schematic/layout recommended it should not be a problem. You can do a pre-scan of your board at many labs to ensure that you will (most likely) meet the requirements.

Hello,

Please find attached the measurements done on boards with BALF-NRF01D3 & nRF51822-QFAAGC. Results show it is in compliance to regulatory standards requirements.
