Downconversion Mixer with LO Buffer/Switch
Note 1: All limits reflect losses of external components. Output measurements taken at IF outputs of the Typical Application Circuit .
Note 2: Performance is guaranteed for f
Note 3: Guaranteed by design and characterization.
Note 4: Measured with external LO source noise filtered so the noise floor is -174dBm/Hz. This specification reflects the effects of all
Note 5: Measured at IF port at IF frequency. LOSEL may be in any logic state.
