Hi：
I found that the datasheet of the adl5521 only has recommended parts for some frequencies. I want to use ADL5521 at 1000MHz, so how should I choose suitable resistors and capacitors?

Hi ZhiZhiZhifly,
You need to use the S-Parameter files for the ADL5521. Found here: https://www.analog.com/media/en/simulation-models/s-parameters/ADL5521_de_embedded_s_params_5V_RevB.zip
Then you use the S-Parameter files in a suitable simulation tool, Keysight ADS, Microwave Office, or other suitable design tool and develop a matching circuit for your frequency of interest.
I have a matching circuit that will cover your frequency band. It is attached below. S-Parameter and NF data as well as the component values required and component location on the ADL5521 are included.

Hi Jim：
Thanks for your reply. I have another question: In the circuit I designed, ADL uses 3.3V power supply, but your design uses 5V power supply. If I use 3.3V power supply, can I directly use the parameters you gave me (as followed)？
Regards
