AC ELECTRICAL CHARACTERISTICS (continued)
(Circuit of Figure 1; V
f
(Circuit of Figure 1, V
wise noted.)
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 application circuit
Note 3: The amplitude and phase unbalance are tested with 50Ω resistors connected from OUT+/OUT- to GND.
