3116C Double-Ridged Waveguide Horn
Frequency Range: 18 GHz – 40 GHz
The Model 3116C Double-Ridged Waveguide Horn is the latest addition to a family of double-ridge guide horns for EMC measurement from ETS-Lindgren. This model corrects the lower gain at the upper end of the frequency range, commonly found in ridged waveguide antennas. Users of this antenna benefit from uniform illumination of target surfaces and accurate gain measurement. In addition, the Model 3116C exhibits high gain and low VSWR across its operational frequency band, accepting moderate power input of 20 watts.
The Model 3116C sweeps from 10 GHz to 40 GHz without stopping for band breaks, making it ideal for automated testing and accepts up to 20 watts of continuous input power. The antenna’s high gain and low VSWR over its operating frequency translates into efficient amplifier use and higher field strengths.
