DRHA18G-PA 18 GHz Dual Rigged Horn Antenna

Model DRHA18G 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 DRHA18G is not intended for RSE testing of intentional radiators.

• 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

DRHA18G Dual Ridged 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 DRHA18G is calibrated as a single unit, so uncertainty values are reduced.
