Conical Inductors for 4GHz ?

Hello,


I am designing a Bias tee at 4GHz. I do not want to use the micro strip lines.

Can anybody suggest me some good conical inductors at this frequency range? or any other better way to design a bias tee ?

I am using a Rogers 3010 substrate and size of the design is the constrain so moving to conical inductors.

Depends on the bandwidth and isolation requirements. Regular wirewound chip inductors operated near it's self resonant frequency may be a simple alternative.

bandwidth is around 500MHz.

I was looking at some coilcraft inductors , would you suggest me to go for those ?
