Hi All,
I'm wondering about component selection regarding a 4-4.5GHz system. I need to select some inductors for RF-chokes in my circuit. There are two inductors of same inductance value but different tolerance and SRF.
I have this duality problem in different cases with similar numbers.
1nH with SRF@6GHz and tolerance with +- 0.1nH
1nH with SRF@15GHz and tolerance with +-0.3nH
I can make my circuit work with high tolerance by selecting other component values accordingly;but I'm not sure how working with a part with SRF close(?!) to my carrier frequency would affect my circuit or better yet is it viable to take that risk?
Any opinions about that? I'm not sure how I can simulate effect of SRF in simulations and I don't want to order some hundreds of wrong inductor.
Best Regards,
