SiGe High-Linearity, 815MHz to 995MHz
Downconversion Mixer with LO Buffer/Switch
_______________________________________________________________________________________

Note 1: All limits include external component losses. Output measurements taken at IF output of the Typical Application Circuit.
Note 2: Operation outside this range is possible, but with degraded performance of some parameters.
Note 3: Compression point characterized. It is advisable not to operate continuously the mixer RF input above +12dBm.
Note 4: 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 5: Guaranteed by design and characterization.
AC ELECTRICAL CHARACTERISTICS (continued)
(MAX9986 Typical Application Circuit, VCC = +4.75V to +5.25V, RF and LO ports are driven from 50Ω sources, PLO = -3dBm to
+3dBm, PRF = -5dBm, fRF = 815MHz to 995MHz, fLO = 960MHz to 1180MHz, fIF = 160MHz, fLO > fRF, TC = -40°C to +85°C, unless
otherwise noted. Typical values are at VCC = +5V, PRF = -5dBm, PLO = 0dBm, fRF = 910MHz, fLO = 1070MHz, fIF = 160MHz, TC =
+25°C, unless otherwise noted.) (Note 1)
