SiGe High-Linearity, 1700MHz to 2200MHz
Downconversion Mixer with LO Buffer/Switch
_______________________________________________________________________________________
3
Note 1: Guaranteed by design and characterization.
Note 2: All limits include external component losses. Output measurements taken at IF output of the Typical Application Circuit.
Note 3: Operation outside this range is possible, but with degraded performance of some parameters.
Note 4: Production tested.
Note 5: Compression point characterized. It is advisable not to operate continuously the mixer RF input above +12dBm.
Note 6: 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.
AC ELECTRICAL CHARACTERISTICS (continued)
(MAX9994 Typical Application Circuit, VCC = +4.75V to +5.25V, RF and LO ports are driven from 50
Ω sources, PLO = -3dBm to
+3dBm, PRF = -5dBm, fRF = 1700MHz to 2200MHz, fLO = 1400MHz to 2000MHz, fIF = 200MHz, fRF > fLO, TC = -40°C to +85°C,
unless otherwise noted. Typical values are at VCC = +5V, PRF = -5dBm, PLO = 0dBm, fRF = 1900MHz, fLO = 1700MHz, fIF = 200MHz,
TC = +25°C, unless otherwise noted.) (Notes 1, 2)
