Amplifier Research ATH18G27 Waveguide Horn Antenna 18 GHz – 26.5 GHz

Description

Amplifier Research ATH18G27 High Gain Waveguide Horn Antenna 18 GHz – 26.5 GHz is a wide band antenna. With a minimum gain of 18.8dB over isotropic, the Model ATH18G27 supplies the high intensity fields necessary for RFI/EMI field testing within and beyond the confines of a shielded room.

The Model ATH18G27 is extremely compact and light weight for ready mobility, yet is built tough enough for the extra demands of outdoor use and easily mounts on a rigid waveguide by the waveguide flange. Part of a family of microwave frequency antennas, the Model ATH18G27 provides the 18.0-26.5GHz response required for many often used test specifications.

The ATH18G27 is ideally suited for use with the AR RF/Microwave Instrumentation Model 40T18G26A and other high power amplifiers in this frequency range.

Features

  • Wide beamwidth, high gain, microwave horn
