Researchers from the HRL labs in California have developed the world’s first graphene-based square-law millimeter detectors. These new detectors sport the highest linear dynamic range (over 60 dB) ever measured in a semiconductor detector. They say that this could lead to better high-bandwidth communications, imaging and radar systems.

The researchers say that their new graphene-based FET detectors out perform the best CMOS or SiGe bipolar detectors by more than 30 dB (linear dynamic range).
