I'm inquiring about PSoC 4200 BLE.

The CY8C4248LQI-BL483 is being used with our wireless IT products. And we plan ship them to South Korea.

Now I would like to confirm whether CY8C4248LQI-BL483 meets Korean RF requirements or not.

According to below link which is RF regulations of Korea, that shows receiver spurious emitting should be less than -54 dBmW (term #12).

http://www.law.go.kr/lsInfoP.do?lsiSeq=196127&efYd=20170726#0000 

But on the other hand "PSoC 4200_BLE data sheet" shows receiver spurious emission only less than -47 dBm (Spec ID# SID356).

Also our existing test results were -53.4 dBm (around 4.8GHz). It's failed.

At 1st I would like to know whether some product already passed RF certificate with CY8C4248LQI-BL483?

If there were some,  I would appreciate if you could give me some idea to address this issue.

Dear Customer,

The device CY8C4248LQI-BL483, as such has emissions (LO Leakage) that could exceed the Korean limit of -54 dBm. But this can be reduced using a low pass matching network in the front end.

The following modules have the same radio as CY8C4248LQI-BL483 and have been certified for Korea.

CYBLE-212019-00

CYBLE-222005-00

CYBLE-214009-00

CYBLE-224110-00

All these modules have implemented a low pass filter based matching network to filter out the LO leakage for receiver. The datasheet of these modules should have the schematics used in them.

Thanks,

Guha
