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.

Maintains Single Lobe Radiation

Like the model 3117, the model 3117-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. The model 3117’s unique design suppresses the propagation of high order modes. The result is an antenna with a well-defined single lobe radiation pattern that outperforms other antennas in its class.

Fitted Amplifier

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 pre-amplifier are an input and output VSWR of 2:1 maximum.

Low Antenna Factor

The result of matching the model 3117 with the pre-amplifier is an antenna that is calibrated as a system. This results in an extremely low AF that is less than -2 dB (1/m) for the entire frequency range.
