Radar Microwave Link (RML) Electromagnetic Compatibility Measurements.

Abstract

Tests were accomplished on two different Microwave Relay Transmitter and Receiver combinations operating in the frequency ranges of 7.125 to 8.4 GHz and 14.4 to 15.25 GHz. Measurements to determine interference characteristics included: receiver off-channel rejection, receiver intermodulation, transmitter spectrums, transmitter intermodulation, and second harmonics. Based on the test results, the adjacent frequency spacing should be at least 20 MHz and 50 MHz for RML-4 and TerraCom equipment, respectively. Additional measurements are recommended on new equipment in the 14.4 to 15.25 GHz range for valid criteria for the handbok in preparation. (Author)
