Endwave Corporation announces a product line of ALC Log Amplifiers. A logarithmic amplifier is a specialty amplifier subsystem that is primarily used as an amplitude detector of input signal strength on the front-end of pulsed radar and other wideband electronic warfare systems. As a log amplifier it provides an output voltage proportional to the logarithm of its input voltage (which is mathematically equivalent to the input power in dBm), the amplitude information is converted to more usable format than other linear detection schemes. In pulse radars, log amplifiers allow the system to process signals with narrow pulse widths and large amplitude variations by effectively compressing a large input dynamic range into smaller, more manageable blocks.
