AC ELECTRICAL CHARACTERISTICS
(Typical application circuit without matching, V
825Ω, P
noted.) (Notes 1, 2)
Note 1: Guaranteed by design and characterization.
Note 2: All limits reflect losses of external components. Output measurements are taken at RF OUT using the typical application
Note 3: Device draws current in excess of the specified supply current when a digital input is driven with a voltage of V
