HMC8410 and inductor

I have a question about HMC8410.
Coilcraft 's 590nH inductor is used for the bias, but my customers say that this is not available.
I must show customers how to choose an alternative inductor.

I think L1 and L2 are choke coils.
What is the performance required for the inductor besides being low in DC resistance and conforming to the GHz band?
Why was the inductor selected from the E48 series?
Is there a reason to be precise?

Best regards
