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: Tests are performed as shown in the confi guration of Figure 1.
Note 3: Specifi cations over the –40˚C to 85˚C temperature range are
assured by design, characterization and correlation with statistical
process control.
Note 4: DSB Noise Figure is measured with a small-signal noise source
at the baseband frequency of 15MHz without any fi ltering on the RF input
and no other RF signal applied.

(Notes 2, 3, 6)
Note 5: 900MHz performance is measured with external RF and LO
matching. The optional output capacitors C1-C4 (10pF) are also used for
best IIP2 performance.
Note 6: For these measurements, the complementary outputs (e.g., I
OUT

) were combined using a 180˚ phase shift combiner.
Note 7: Large-signal noise fi gure is measured at an output frequency of
198.7MHz with RF input signal at f
LO
–1MHz. Both RF and LO input signals
are appropriately bandpass fi ltered, as well as baseband output.
