Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: 450MHz, 900MHz and 2450MHz performance measured with the
following external RF input matching. 450MHz: C5 = 8.2pF, 5mm away
from Pin 3 on the 50Ω input line. 900MHz: C5 = 2.2pF at Pin 3. 2450MHz:
L3 = 3.9nH at Pin 3. See Figure 2.

Note 3: Specifications over the –40°C to 85°C operating temperature
range are assured by design, characterization and correlation with
statistical process controls.
Note 4: SSB Noise Figure measurements performed with a small-signal noise
source and bandpass filter on RF input, and no other RF signal applied.
