SL2521 and SL2522 series of log amplifiers, and exhibits a
superior stability performance. The amplifier is a successive
detection type which provides linear gain and accurate loga-
rithmic signal compression over a wide bandwidth. The two
stages can be operated independently.
can be used for IFs between 30-650MHz whilst achieving
greater than 65dB dynamic range with a log accuracy of
< 1.0dB. The balanced limited output also offers accurate
phase information with input amplitude.
