Characterization Data

Characterization Data

The following charts illustrate the characteristics of a typical RM912 Power Amplifier tested in the

evaluation board described in the following section. The amplifier was selected by characterizing a

group of devices and choosing a part with average electrical performance at both nominal and

worst case (limit) conditions. Figures 1 through 4 illustrate the digital signal characteristics and

Figures 5 through 8 illustrate the analog characteristics of the RM912.
