LO Input Power
Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: 450MHz, 900MHz and 3500MHz performance measured with
external LO and RF matching. See Figure 1 and Applications Information.

Note 3: Specifi cations over the –40°C to 85°C 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 fi lter on RF input, and no other RF signal
applied.
