HIGH-SIDE LO INJECTION (continued)
( Typical Application Circuit with tuning elements outlined in Table 1, V CC = 4.75V to 5.25V, RF and LO ports are driven from 50
Ω
sources, Typical values are for T C = +25°C, V CC = 5.0V, P LO = 0dBm, f RF = 3500MHz, f LO = 3800MHz, f IF = 300MHz. Parameters
are guaranteed by design and not production tested.) (Note 6)
Note 5: Not production tested. Operation outside this range is possible, but with degraded performance of some parameters. See
the Typical Operating Characteristics.
Note 6: All limits reflect losses of external components, including a 0.8dB loss at f IF = 300MHz due to the 4:1 impedance trans-
former. Output measurements were taken at IF outputs of the Typical Application Circuit.
Note 7: 100% production tested for functional performance.
Note 8: 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 9: Maximum reliable continuous input power applied to the RF port of this device is +12dBm from a 50 Ω source.
