(1)

Electrical table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very

limited self-heating of the device such that TJ = TA. No specification of parametric performance is indicated in the electrical tables

under conditions of internal self-heating where TJ > TA.

(2)

All limits are specified by design or statistical analysis.

(3)

Typical values represent the most likely parametric norm.

(4)

Power in dBV = dBm + 13 when the impedance is 50Ω.

(5)

Slope and intercept calculated from graphs VOUT vs RF input power where the current is obtained by division of the voltage by 20kΩ.

(6)

The output is not short-circuit protected internally. External protection is necessary to prevent overheating and destruction or adverse

reliability.
