RTL-4 Series Logarithmic Hybrid Amplifiers
80dB Dynamic Range
+/-1 dB Linearity
DC Coupled Video
Built-in Voltage Regulation
Excellent Pulse Response


 RTI has developed a series of hybrid log amplifiers that are small in size, light in weight, and high on  reliability. These units provide a detected video output voltage logarithmically proportional to the  input IF power. Specifically designed for use in electronic warfare and radar receiving systems,  these units deliver fast rise and fall time pulse characteristics.
