SiGe High-Linearity, 1700MHz to 2200MHz
Downconversion Mixer with LO Buffer/Switch
_______________________________________________________________________________________

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.
