Typical Operating Characteristics

(

Note 5: Operation outside this frequency band is possible but has not been characterized. See the

Typical Operating Characteristics.

Note 6: Guaranteed by design and characterization.

Note 7: All limits reflect losses of external components. Output measurements taken at IF outputs of

Typical Application Circuit.

Note 8: Production tested.

Note 9: Two tones 3MHz spacing, -5dBm per tone at RF port.

Note 11: IF return loss can be optimized by external matching components.
