3117-PA Double-Ridged Waveguide Horn with Pre-Amp
ETS-LINDGREN’S MODEL 3117-PA is a special version of our popular Model 3117 Double-Ridged Wave-guide Horn Antenna, fitted with a pre-amplifier package and calibrated as a single unit. By doing this, any possible mismatches between antenna and pre-amplifier are taken into account in the antenna factor (AF), which is provided with this unit. The antenna is ideal as a receive antenna for emissions testing above 1 GHz.
The pre-amplifier attached to the antenna has a frequency range of 1 GHz to 18 GHz and a typical gain of 48 dB. The gain flatness across the range is ± 2.5 dB. The pre-amplifier has a maximum noise figure of 3 dB maximum with the typical noise figure being 2 dB. The power output is +17 dB minimum at the 1 dB point. The input and output characteristics of the preamplifier are an Input and output VSWR of 2:1 maximum.
