Downconversion Mixer with LO Buffer/Switch
AC ELECTRICAL CHARACTERISTICS (UPCONVERTER OPERATION)
(MAX2039 Typical Application Circuit , V CC = +4.75V to +5.25V, T C = -40°C to +85°C, P LO = -3dBm to +3dBm, P IF = 0dBm, f RF =
1700MHz to 2200MHz, f LO = 1500MHz to 2000MHz, f IF = 200MHz, f RF = f LO + f IF , unless otherwise noted. Typical values are at V CC
= +5V, P IF = 0dBm, P LO = 0dBm, f RF = 1900MHz, f LO = 1700MHz, f IF = 200MHz, T C = +25°C, unless otherwise noted.) (Note 2)

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.
