Not production tested. Operation outside this range is possible, but with degraded performance of some parameters. See
the Typical Operating Characteristics . Performance is optimized for RF frequencies of 824MHz to 915MHz.
All limits reflect losses of external components. Output measurements taken at IF outputs of Typical Application Circuit .
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 the Application Note 2021: Specifications and
Measurement of Local Oscillator Noise in Integrated Circuit Base Station Mixers .
Measured at IF port at IF frequency. LOSEL may be in any logic state.
Limited production testing.
