Note 5:
Operation outside this range is possible, but with degraded performance of some parameters. See the
Typical Operating
Characteristics section.
Note 6:
Not production tested.
Note 7:
All values reflect losses of external components, including a 0.6dB loss at f
IF
= 350MHz and a 0.8dB loss at
f
IF
= 1000MHz due to the 1:1 transformer. Output measurements were taken at IF outputs of the
Typical Application Circuit.
Note 8:
Guaranteed by design and characterization.
Note 9:
100% production tested for functionality.
Note 10: Additional improvements (of up to 4dB to 6dB) in spurious responses can be made by increasing the LO drive to +6dBm.
Note 11: The LO return loss can be improved by tuning C9 to offset any parasitics within the specific application circuit. Typical
range of C9 is 10pF to 50pF.
