Amplifier Research AT4640 Microwave Horn Antenna

The Model 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 ModelAT4640 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, the Model AT4640 provides the 18.0-26.5GHz response required for many often used test specifications.

The AT4640 is ideally suited for use with the AR Models 40T18G26 and other high power amplifiers in this frequency range.
