Inductor for High Frequency

[camel_RF]

Hi

Anyone can tell me how do I determine a suitable indcutor value for my design?
Freq= 10MHz to 50Ghz
Reason = RF choke

Thanks.

You will need more than one in series. With this wide frequency range the self resonant frequency of one useful at 10 MHz will be well less than 50 GHz.

It is difficult to make one for a decade of bandwidth much less your 3.7 decades.

r u talking about on-chip or off-chip inductor?

for on-chip inductor, I think conventional inductors will not operate to such a high frqency as 50GHz, u need bottom isolation sheet of something.

for off-chip inductor, I think an inductor with intermediate value can do

You can take 1cm of wire, it has inductance and wery high frequency self resonance. But I am not shure you will be satisfied.

the high frequency is too high !
u can divide the range to a few part.
it is reasonable!

it is very hard to implement in the one part
