SiGe High-Linearity, 2000MHz to 3000MHz

Upconversion/Downconversion Mixer with LO Buffer

6 ______________________________________________________________________________________

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 50I source.
