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: Specifi cations over the –40ºC to +85ºC temperature range are
assured by design, characterization and correlation with statistical process
controls.
Note 3: A 1:4 input transformer is used for the input matching to 50Ω
source.
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
–30dBm to 2dBm. The dynamic range is defi ned as the range over which
the linearity error is within ±1dB.
ELECTRICAL CHARACTERISTICS
The l denotes the specifi cations which apply over the full operating
temperature range, otherwise specifi cations are at T
