Why Do We Need to ponents?
• Verify specifications of “building blocks” for plex RF systems
• Ensure distortionless transmission
munications signals
– linear: constant amplitude, linear phase / constant group delay
– nonlinear: harmonics, intermodulation, compression, AM-to-PM conversion
• Ensure good match when ab
