Part Number: CC1120


I have a question as regarding CC1120RHBR

We've already applied CC1120RHBR to new bidet with one of biggest bidet manufatuere in Korea named by Darim https://www.daelimbath.com/

1. APPLICATION : NEW BIDET

2. MP PLAN : WITHIN 3Q

3. MP Q'TY : 50K - 100K // YEAR at least  (The Q'ty is can be changed  depends on the customer feedback) Usually 1 aprtment 2 bedroom and so 2 bidet.

4. Currently situation : We'd like to get the certification from Korea ele..  

I have a question as below

The difference in the size of the main frequency and harmonics of the radio wave certification items should be greater than 40 dB, but there is no room for it.

How can I handle that ?

    "The difference in the size of the main frequency and harmonics of the radio wave certification items should be greater than 40 dB, but there is no room for it.": Not sure if I understand the question. Do you mean that the power of the harmonics need to be 40 dB lower (40 dBc) than the power of the harmonics? 

    If that is the case, please note that our reference designs passed ETSI and FCC regulations which has similar requirements. I would recommend buying a few CC1120 EMs and do some conducted measurements to start with.
