Note 1:
Guaranteed by design and characterization.
Note 2:
All limits reflect losses of external components. Output measurements taken at IF OUT of
Typical Application Circuit
.
Note 3:
Production tested.
Note 4:
Two tones at 1MHz spacing, -5dBm per tone at RF port.
Note 5:
Measured at IF port at IF frequency. f
LO1
and f
LO2
are offset by 1MHz.
Note 6:
IF return loss can be optimized by external matching components.
