MAX2042A
SiGe High-Linearity, 1600MHz to 3900MHz
Upconversion/Downconversion Mixer with LO Buffer
3.3V Supply, RF = 2000MHz to 2900MHz, HIGH-SIDE LO INJECTION AC ELECTRICAL

Note 5: Not production tested.
Note 6: Operation outside this range is possible, but with degraded performance of some parameters. See the Typical Operating
Characteristics.
Note 7: All limits reflect losses of external components, including a 0.5dB loss at f
IF
= 300MHz due to the 1:1 impedance
transformer. Output measurements were taken at IF outputs of the Typical Application Circuit.
Note 8: 100% production tested for functional performance.
Note 9: Measured with external LO source noise filtered so that the 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 Application Note 2021:
Specifications and Measurement of Local Oscillator Noise in Integrated Circuit Base Station Mixers.
Note 10: Maximum reliable continuous input power applied to the RF or IF port of this device is +12dBm from a 50I source.
