Note 1:
Specifications over T

C.
Note 2:
Idle current is controlled by external DAC for best efficiency over the entire output power range.
Note 3:
Parameter measured with RF modulation based on IEEE 802.11b standard.
Note 4:
Power gain is guaranteed over this frequency range. Operation outside this range is possible, but is not guaranteed.
Note 5:
Output two-tone third-order intercept point (OIP3) is production tested at T
A
= +25
°
C. The OIP3 is tested with two signals at
f1 = 2.450GHz and f2 = 2.451GHz with fixed P
IN
.
Note 6:
Min/max limits are guaranteed by design and characterization.
Note 7:
The total turn-on and turn-off times required for PA output power to settle to within 0.5dB of the final value.
Note 8:
Excludes PC board loss of approximately 0.15dB.
Note 9:
See
Typical Operating Characteristics
for statistical variation.
