Amplifier Research AT4640 Microwave Horn Antenna

The Amplifier Research AT4640 (also know as model number ATH18G27-1) is a wide band, low gain, wide beamwidth, high power microwave horn antenna. With a minimum gain of 8.8dB over isotropic, the Amplifier Research AT4640 supplies the high intensity fields necessary for RFI/EMI field testing within and beyond the confines of a shielded room. The Model AT4640 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, AT4640 provides the 18.0-26.5GHz response required for many often used test specifications.

The Amplifier Research AT4640 Microwave Horn Antenna is ideally suited for use with the AR Models 40T18G26 and other high power amplifiers in the aforementioned frequency range.
