Note 1: Guaranteed by design and characterization.

Note 2: Two tones at 1.9GHz and 1.901GHz at -32dBm per tone

Note 3: Two tones at 1.9GHz and 1.901GHz at -22dBm per tone

Note 4: Mixer operation guaranteed to this frequency. For optimum gain, adjust output match. See the Typical Operating

Characteristics for graphs of IFIN and IFOUT Impedance vs. IF Frequency.

Note 5: At this LO drive level the mixer conversion gain is typically 1dB lower than with -10dBm LO drive.

Note 6: Two tones at 400MHz and 401MHz at -32dBm per tone.

Note 7: Transmit mixer output at -17dBm.

Note 8: Calculated from measurements taken at VGC = 1.0V and VGC = 1.5V.

Note 9: Time from RXEN = low to RXEN = high transition until the combined receive gain is within 1dB of its final value. Measured

with 47pF blocking capacitors on LNAIN and LNAOUT.

Note 10: Time from TXEN = low to TXEN = high transition until the combined transmit gain is within 1dB of its final value. Measured

with 47pF blocking capacitors on PADRIN and PADROUT.
