SL2524

SL2524 1.3GHz Dual Wideband Logarithmic Amplifier DS4548 - 2.1 July 1995 The SL2524 is a pin compatible replacement for the 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 logarithmic signal compression over a wide bandwidth. The two stages can be operated independently. When six stages (three SL2524s) are cascaded the strip 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.
