In the charts shown here, the PAT’s performance is overlaid with ATS’s performance up to 12GHz. The attenuation chart on the left clearly shows that PAT starts changing at about 8GHz even though still remaining within the specifications. The ATS series demonstrates a horizontal trend until about 25GHz. In VSWR, PAT demonstrates a smaller VSWR up to 7GHz, but it shows a significant upward trend after 7GHz. The ATS has fluctuation but it does not exceed the specifications.
