SL531, 250Mhz TRUE LOG IF Amplifier
The SL531 transfer characteristic has two regions For small input signals it has a nominal gain of 10 dB.
at large signals the gain falls to unity (see Fig 7) This is achieved by operating a limiting amplifier and a unity gain amplifier in parallel (see Fig 3) Tr1 and Tr4 comprise the long tailed pa

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 bandwi
