Typical Performance Characteristics (L-Band) (Continued)

Plots are exemplary only, to show typical performance and provide a frame of reference. Typical test conditions (TTC)

VDD = 1.8V, TA = +25°C, and PIN < -48dBm, unless otherwise noted. Extreme Characterization Conditions (ECC) are

VDD = 1.7V to 1.9V, TA = -40°C to +85°C.
