Note 1: All limits reflect losses of external components. Output measurement taken at IF port of Typical Application Circuit.
Note 2: The lower IF frequency limit of 0MHz is limited by the external IF transformer.
Note 3: Measured with external LO source noise filtered so its noise floor is not a contributor. Measured with: f

LO
= 2190MHz, using a 190MHz SAW filter on the IF port. This specification reflects the effects of
all SNR degradations in the mixer, including the LO noise as defined in Maxim Application Note 2021.
Note 4: Maximum reliable continuous input power applied to the RF or IF port of this device is +15dBm from a 50Ω source.
Note 5: Typical Operating Characteristics show LO drive extended to +6dBm
Note 6: Measured IF port at IF frequency. f

Note 7: IF return loss can be optimized by external matching components.
