Torex GPS LNA S Parameter Simulation
■Design reference data for XC2401/XC2406/XC2407/XC2408
These 4 charts are S parameters measured without the external components required to match to 50Ω.
Please use them as reference data when you design GPS block.
XC2401A8167R-G, XC2406A816UR-G, XC2407A816UR-G and XC2408A816UR-G have each S2P file.
The S2P files for downloading are the same data as below.
Please visit each individual product information page on Torex website for downloading.
