Echotek Series RFM-1802RF with Synthesizer ADV-1800S Dual-Channel Wideband Microwave Tuner

Product Description

The Echotek™ Series RFM-1802RF with Synthesizer ADV-1800S Dual-Channel Wideband Microwave Tuner is an ultra high-performance tuner,
featuring low phase noise and extremely fast tuning speed. These critical characteristics are provided by the direct digital synthesis (DDS), which uncouples tuning speed from phase noise, thereby creating a high-performance tuner. The two high-performance receivers and frequency agile synthesizer are compressed into a two-slot VME solution.

The product described in this data sheet is ITAR-controlled. It may not be exported or transferred to a foreign person, whether in the United States or abroad, without first obtaining appropriate authorization from the U.S. Department of State, Directorate of Defense Trade Controls.
