PARAMETER

Note 1:

Guaranteed by design and characterization.

Note 2:

Operation outside of this specification is possible, but performance is not characterized and is not guaranteed.

Note 3:

Two input tones at -25dBm per tone.

Note 4:

This spurious response is caused by a higher-order mixing product (2x2). Specified RF frequency is applied and IF output
power is observed at the desired IF frequency (70MHz).
