Downconversion Mixer with LO Buffer/Switch

3.3V SUPPLY, LOW SIDE INJECTION AC ELECTRICAL CHARACTERISTICS (continued)

(Typical Application Circuit (see Table 1). R1 = R4 = 681I, R2 = R5 = 1.43kI. Typical values are at VCC = 3.3V, PRF = -5dBm, PLO = 0dBm,

fRF = 1450MHz, fLO = 1310MHz, fIF = 140MHz, TC = +25NC, unless otherwise noted.) (Note 7)

Note 5: 100% production tested for functionality.

Note 6: Not production tested. Operation outside this range is possible, but with degraded performance of some parameters. See

the Typical Operating Characteristics section.

Note 7: All limits reflect losses of external components, including a 0.5dB loss at fIF = 140MHz due to the 4:1 transformer. Output

measurements were taken at IF outputs of the Typical Application Circuit.

Note 8: Maximum reliable continuous input power applied to the RF or IF port of this device is +12dBm from a 50I source.

Note 9: Not production tested.

Note 10: 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 Application Note 2021: Specifications and

Measurement of Local Oscillator Noise in Integrated Circuit Base Station Mixers.
