The ERDLVA-18G40G-65-50-1 from Quantic PMI is an Extended Range Detector Log Video Amplifier (ERDLVA) that operates from 18 to 40 GHz. It has a logging range from -65 to 0 dBm and a tangential signal sensitivity (TSS) of -68 dBm. This ERDLVA has a log linearity of ±1.5 dB, a 50 mV/dB log slope, and a typical rise time of 10 ns. It can handle a CW input power of up to 20 dB with a SWR of 2.50:1. This log video amplifier offers a faster response time and improved linearity with the ability to be interfaced with a long cable (30 meters) while maintaining high speed and flatness.
The ERDLVA-18G40G-65-50-1 requires a DC supply of +9 to +12 V or -11.5 to -15 V and consumes less than 330 mA of current. It is available in a nickel-plated module that measures 41 x 38 x 7.9 mm and has SMA female connectors.
