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 .
100% production tested for functional performance.
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 50 I source.
