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.
