Note 1: See Tables 1–5 for operational mode selection.
Note 2: A total of 36 devices from 3 different wafer lots are used to determine the standard deviation. The lots were selected to rep-
resent worst-case process conditions.
Note 3: Operation is characterized for the frequencies specified in the conditions; for other frequencies in the band, see Tables 8–12
for LNA and mixer S parameters.
Note 4: Guaranteed by design, characterization, and production functional test.
Note 5: Guaranteed by design and characterization.
Note 6: For cellular band, RF inputs are -25dBm each tone at 881MHz and 882MHz, f
LO
= 1091MHz. For PCS band, RF inputs are
-25dBm each tone at 1960MHz and 1961MHz, f
LO
= 2170MHz. For IIP3 vs. I
