Note 1: Guaranteed by design and characterization.
Note 2: All limits reflect losses of external components. Output measurements taken at IF outputs of Typical Application Circuit.
Note 3: Production tested.
Note 4: Two tones 3MHz spacing, -5dBm per tone at RF port.
Note 5: Measured at IF port at IF frequency. f

LO1

and f

LO2

are offset by 1MHz.

Note 6: IF return loss can be optimized by external matching components.
Note 7: Operation outside this frequency band is possible but has not been characterized. See the Typical Operating Characteristics.
