SL521

150MHz WIDEBAND LOG AMPLIFIER

The SL521A, B and C are bipolar monolithic Integrated

circuit wideband amplifiers, intended primarily for use in

successive detection logarithmic IF strips, operating at centre

frequencies between 10MHz and 100MHz The devices

provide amplification, limiting and rectification, are suitable for

direct coupling and incorporate supply line decoupling The

mid-band voltage gain of the SL521 is typically12dB(4times)

The SL521A, B and C differ mainly in the tolerance of voltage

gain and upper cut-off frequency

The device is also available as the 5962-90792 which has

guaranteed operation over the full Military Temperature

Range and is screened to MIL-STD-883 Class B. Data is

available separately
