External loop filter for CC1050

Other Parts Discussed in Thread: CC1050, CC1070

Hello,

I'm using the CC1050 as an CW signal generator for 433MHz. To improve the output spectrum I want to use an external loop filter, but I can't find any information on how to design it. Especially there is no information about kVCO.

Thank you

External loop filter for CC1050 is not recommended. In fact, I would not use CC1050 for new design. Have a look at CC1070 instead, the phase noise is significantly better than for CC1050.

Thanks for that information. The problem is that i have an existing Board and i don't wont to redesign that if not absolutely necessary.
