RTL-8 Series Logarithmic Hybrid Amplifiers

Bookmark and Share


RTI has developed a series of hybrid log amplifiers that are 30% smaller than our RTL-4 Series without sacrificing the electrical performance characteristics found in the RTL-4 series log amplifiers.

Design Note: Radar Technology can customize any of our products to meet your individual system requirements. RTI also offers many Form, Fit, Function replacements to old RHG Electronics Amplifiers.
