ABSOLUTE MAXIMUM RATINGS

DC ELECTRICAL CHARACTERISTICS

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional

operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to

absolute maximum rating conditions for extended periods may affect device reliability.

Note 1: Guaranteed by design and characterization.

Note 2: 1.9GHz and 1.901GHz tones at -30dBm per tone.

Note 3: 1.9GHz and 1.901GHz tones at -21.5dBm per tone.

Note 4: Mixer operation is guaranteed to this frequency. For optimum gain, adjust IF output match. See the IF Output Impedance

(single ended) vs. Frequency graph in the

Typical Operating Characteristics.

Note 5: Time from RXEN = low to RXEN = high, until the combined receive gain is within 1dB of its final value. Measured with 47pF

blocking capacitors on LNAIN and LNAOUT.

Note 6: At this LO drive level, the mixer conversion gain is typically 1dB lower than with -10dBm LO drive.
