Typical perForMance characTerisTics

Output Voltage vs RF Input Power

Linearity Error vs RF Input Power

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: The LTC5582 is guaranteed functional over the temperature range

–40°C to 85°C.

Note 3: Logarithmic Intercept is an extrapolated input power level from the

best fitted log-linear straight line, where the output voltage is 0V.

Note 4: Operation over a wider frequency range is possible with reduced

performance. Consult the factory for information and assistance.

Note 5: The linearity error is calculated by the difference between the

incremental slope of the output and the average output slope from

–50dBm to –5dBm. The dynamic range is defined as the range over which

the linearity error is within ±1dB.
