Note 1: Min and max limits are guaranteed by test above TA = +25°C and guaranteed by design and characterization at TA = -40°C.

The power-on register settings are not production tested. Recommended register setting must be loaded after VCC is supplied.

Note 2: Guaranteed by design and characterization.

Note 3: The nominal part-to-part variation of the RF gain step is ±1dB.

Note 4: Two tones at +25MHz and +48MHz offset with -35dBm/tone. Measure IM3 at 2MHz.

Note 5: Tx I/Q inputs = 100mVRMS.
