# ADRV9009 - The matching network topology

Hello,

I want to configure matching network topology for ADRV9009 so that it can operate at different frequency bands, for example from 625Mhz to 2815Mhz. But there are some components that are mentioned in table 16 (page 126 ADRV9009 datasheet ) that I cannot find their position in the topology for transmitter 1 such as 313 and 310. Here are the pictures of the matching network topology and table 16 that are mentioned in the datasheet. Could you help me with this problem? Thank you.
