(1) Test levels: (A) 100% tested at 25°C. Overtemperature limits by characterization and simulation. (B) Limits set by characterization and
simulation. (C) Typical value only for information.
(2) The 1-dB compression point is measured at the load with 50-Ω double termination. Add 3 dB to refer to amplifier output.
