This is an interesting and useful component, in that it contains a logarithmic amplifier such that it produces a voltage proportional to the RF input in decibels.

FEMTO’s logarithmic wideband voltage amplifier HLVA-100 has a wide dynamic range of 0dB to 80dB, with DC coupled input and a fast rise/fall time of 5ns for a 40dB step.

LMV225, LMV226 and LMV228National's LMV225, LMV226 and LMV228 are log amp RF power detectors with multi-band frequency ranges from 450 MHz to 2 GHz. These devices provide an accurate temperature and ...

The circuit shown is a differential amplifier that not only offers programmability but also provides a logarithmic-type gain (Fig. 1). The traditional gain-setting resistors of the amplifier, R1 ...

The principle of the construction of a logarithmic amplifier using semi-conductor Germanium diodes as logarithmic elements was described in Report B-056, Serial No. 1953/14. This report describes ...

This report describes a compact logarithmic amplifier using a semi-conductor as the logarithmic element. Very high writing speeds are obtainable with this instrument, which may therefore be used ...

In amplifier discussions, we don’t normally talk about the specifics of an amplifier’s gain because it involves writing formulae and a background in engineering, mathematics, and an understanding of ...

Plessey Semiconductors has announced the launch of a logarithmic/limiting amplifier with 75dB dynamic range. The PS13201 log amp is a pin for pin, drop in compatible replacement for the original ...
