Other Parts Discussed in Thread: CC1100, CC1101,
Hello,
We developed a system around 2007 with the CC1100 implemented. This units have passed the EN300220 test. Last year we finished a new version of the main unit.
During a verification of this new unit delivered from a test facility. they have discovered quite large side emmiting issues. The frquency spectrum indicate a to wide transmitting burst.
The question is if you have any suggestions on how to reduce the bandwith. we have already reduced the output power and this gave us improvement but not enough. So the next step is if we have to do more changes in the register settings and/or HW considerations.
Attached you find the picture of the spectrum issue and also the gerber
