Note 7:
Not production tested.
Operation outside this range is possible, but with degraded performance of some parameters. See the Typical
Operating Characteristics .
All limits reflect losses of external components, including a 0.8dB loss at f IF = 300MHz due to the 4:1 impedance trans-
former. Output measurements were taken at IF outputs of the Typical Application Circuit .
Note 8: Guaranteed by design and characterization.
Note 9: 100% production tested for functional performance.
Note 10: Maximum reliable continuous input power applied to the RF port of this device is +12dBm from a 50 I source.
Note 11: Measured with external LO source noise filtered so that the noise floor is -174dBm/Hz. This specification reflects the
effects of all SNR degradations in the mixer including the LO noise, as defined in Application Note 2021: Specifications
and Measurement of Local Oscillator Noise in Integrated Circuit Base Station Mixers.
