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 50

Ω 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.
