Note 1: 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 2: Compression point characterized. It is advisable not to continuously operate the mixer RF or IF input above +15dBm.
Note 3: Measured with external LO source noise filtered so 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.
Note 4: Refer to the MAX2043 for improved LO leakage of -52dBm typical.
