Note 1: Guaranteed by design and characterization.
Note 2: All limits include external component losses. Output measurements taken at IF port for downconverter and RF port for
upconverter from the Typical Application Circuit.
Note 3: Operation outside this range is possible, but with degraded performance of some parameters.
Note 4: Compression point characterized. It is advisable not to continuously operate the mixer RF or IF input above +15dBm.
Note 5: Measured with external LO source noise filtered such 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 Maxim Application Note 2021.
