Upconversion/Downconversion Mixer with LO Buffer
+3.3V SUPPLY AC ELECTRICAL CHARACTERISTICS
(UPCONVERTER OPERATION)
( Typical Application Circuit with tuning elements outlined in Table 2 , RF and LO ports are driven from 50 I sources. Typical values
are for T C = +25 N C, V CC = +3.3V, P IF = 0dBm, P LO = 0dBm, f RF = 2600MHz, f LO = 2400MHz, f IF = 200MHz, unless otherwise
noted.) (Note 7)

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 fIF = 300MHz due to the 1:1 impedance trans-
former. 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. 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 port of this device is +20dBm from a 50 I source.
