The SL531 C is a wide band amplifier designed for use in logarithmi c IF amplifiers of the true log type. The input and log output of a true log amplifier are at the same frequency i e detection does not occur. In successive detection log amplifiers (using SL521 SL1521 types) the log output is detected.The small signal gain is 10dB and bandwidth is over 500MHz. At high signal levels the gain of a single stage dropstounity. A cascade of such stages give a close approximation to a log characteristic at centre frequencies between 10and 200MHz.

An important feature of the device SL531 is that the phase shift is nearly constant with signal level. Thus any phase information on the input signal is preserved through the strip.The device is also available as the 5962-92084 which has guaranteed operation over the full Military Temperature Range and is screened to MIL-STD-883 Class B. Data is available separately
