Selective Super Low Noise Preamplifier MKU LNA 144 A

This selective super low noise preamplifier uses the latest PHEMT transistor technology from Agilent. Due to his high technical performance - low noise figure, high gain and very high IP3 - it is the ideal preamplifier for contest operation as well as EME, Meteorscatter, Aurora and tropo DX.

Features
