MAX2029
High-Linearity, 815MHz to 1000MHz Upconversion/
Downconversion Mixer with LO Buffer/Switch
4 _______________________________________________________________________________________
Note 1: All limits include external component losses. Output measurements are taken at IF or RF port of the
Typical Application Circuit
.
Note 2: Operation outside this range is possible, but with degraded performance of some parameters.
Note 3: Guaranteed by design.
Note 4: Compression point characterized. It is advisable not to continuously operate the mixer RF/IF inputs above +15dBm.
Note 5: Measured with external LO source noise filtered, so its noise floor is -174dBm/Hz at 100MHz offset. This specification reflects the
effects of all SNR degradations in the mixer, including the LO noise as defined in
Maxim Application Note 2021.
