I have a document, the document name is [AN:Range Extender solution for Qn902x-20160718], but there is no QN9021 circuit, how to solve this?

Hello Zheng Jung-hung,

To which document are you refering to? I am not able to find such document.

The difference between QN9020 and QN9021 is the number of pins in the package, but also some of the RF matching components are also different. Please refer to the QN902x Datasheet for information on the matching components values and reference schematics.

Regards,

Gerardo
