Typical User Controlled Attenuation (UCA) Test Data 

 Notes:

1. Power measurements were made using a VDI Erickson Power Meter.

2. The UCA voltage reduces the module's output power. The data presented in this graph was measured by VDI under specific test conditions. These graphs are intended to be used as examples to show a module's nonlinearity and frequency dependence. The exact shape of the curves will vary significantly depending on the measurement conditions, including operating temperature, modulation rate, duty cycle, and load impedance. The performance is also unique to the frequency band and specific serial number of the module. Finally, it should be noted that for large attenuation values the multipliers can become under-pumped and may generate undesired harmonics at increased levels.
