f
Dual, SiGe, High-Linearity, 1700MHz to 2200MHz
Note 5: Not production tested. Operation outside this range is possible, but with degraded performance of some parameters. See
Note 6: All limits reflect losses of external components, including a 0.65dB loss at f
Note 7: Maximum reliable continuous input power applied to the RF or IF port of this device is +12dBm from a 50Ω source.
Note 8: Guaranteed by design and characterization.
Note 9: Measured with external LO source noise filtered so the noise floor is -174dBm/Hz. This specification reflects the effects of
Note 10: Limited production testing.
