ETS-Lindgren's Model 3115-PB is our popular Model 3115 Double-Ridged Waveguide Horn Antenna, fitted with an updated pre-amplifier package and calibrated as a single unit.  In this configuration, any possible mismatches between antenna and pre-amplifier are taken into account in the antenna factor (AF) which is provided with this unit. Please note, the 3115-PB is not intended for RSE testing of intentional radiators.

Key Product Information

​Frequency Range

This antenna covers the 1 GHz to 18 GHz range making it ideal as a receive antenna for any emissions testing above 1 GHz.

Designed for MIL-STD-461

The 3115 Horn Antenna (without pre-amplifier) is identical to the antenna described in MIL-STD-461 RE102, for emissions testing above 1 GHz.

Fitted Amplifier

The pre-amplifier has a frequency range of 1 GHz to 18 GHz and a typical gain of 28 dB. The gain flatness across the range is ± 2.5 dB. The pre-amplifier has a maximum noise figure of 4 dB maximum with the typical noise figure being 3 dB. The power output is +17 dB minimum at the 1 dB point. The input and output characteristics of the pre-amplifier are an input and output VSWR of 2:1 maximum.

Calibrated as Single Unit

The 3115-PB is calibrated as a single unit, so uncertainty values are reduced.
