Key Features
  • 18 GHz to 40 GHz Frequency Range
  • Maintains Single Lobe Radiation
  • Fitted with Pre-Amplifier for Increased Sensitivity
  • Extremely Low AF
  • Flexible Mounting

ETS-Lindgren's Model 3116C-PA is a special version of our popular Model 3116C Double-Ridged Waveguide 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 18 GHz. Please note, the 3116-PA is not intended for RSE testing of intentional radiators.

Product Features

Frequency Range

This antenna covers the 18 GHz to 40 GHz range when fitted with the pre-amplifier. The range is determined by the pre-amplifier module. The range makes it ideal as a receive antenna for any emissions testing above 18 GHz.

Maintains Single Lobe Radiation

Like the model 3116C, the model 3116C-PA maintains a single main lobe pattern in the direction of the horn axis over its frequency range. This characteristic is essential for even distribution of electromagnetic energy on a target surface, and accurate measurement of gain and emissions.

Fitted Amplifier

The pre-amplifier attached to the antenna has a frequency range of 18 GHz to 40 GHz and a typical gain of 35 dB. The gain flatness across the range is 3 dB and the noise figure is 3.7 dB. The power output is +8 dB minimum at the 1 dB point. The input and output characteristics of the pre-amplifier are an input and output VSWR of 2.9: 1 maximum. The operating temperature ranges from -40C to +75C (-40F to +167F).

Low Antenna Factor

The result of matching the model 3116C with the pre-amplifier is an antenna that is calibrated as a system and it provides an extremely low AF that is less than 15 dB (1/m) for the entire frequency range.
