Inductor value in LNA Design

[whitewiz]

I am currently designing 900MHz Low Noise Amplifier for the project but the inductor value is pretty high around 1uH.

From the catalong(**broken link removed**), I could not find the 1uH inductor operating at 900MHz.

I am so wondering I need to use only 1uH at 900Mhz or just use 1uH at any frequency range for real design. Do I need to MATCH the inductor value with Test Frequency ?

Thanks

I think 1uH is very big try to reduce it

is this inductor as RF chock ?

if it is try to use the 120 to 150 NH , they will work as RF chocks

is there any off chip chock in hundreds NH?

1/2Pisqrt(LC) =f. try to take capacitance value unknown and take known inductance.u can have a RLC tuned circuit.

R=2Pisqrt(L/C).

which tool u r using.

yeah , there is hunders of nH coils from murata , and coil craft
