Description

Model AH-640 is a broadband linearly polarized double ridged waveguide horn antenna designed specifically for Electromagnetic Interference testing. This antenna can be used for receive as well as transmit applications for the frequency range of 26.5 GHz - 40 GHz.

This antenna has a high gain; at least 23 dBi over the entire frequency range. This antenna can accept up to 5 Watts of input power at its terminals in continuous mode in the applicable frequency range for generating electromagnetic fields.

The AH-640 Horn antenna has a K type connector which can mate with SMA type connectors. The antenna is constructed using lightweight aluminum with a corrosion resistant finish. The oval rear plate has a 1/4" x 20 threaded hole for mounting to the Com-Power AT-100 tripod.

Features

• Broadband - 26.5 GHz to 40 GHz
• High Gain - Lower Floor Noise for Emissions
• Individual Calibration

Com-Power AH-640 Application

The AH-640 was designed for EMC testing, but it can also be used for antenna gain pattern measurements, surveillance, and other applications. The wide frequency band makes the AH-640 antenna suitable for sweep measurements, reducing the need for antenna switching during the test.

High gain reduces input power requirements to achieve the desired field levels for immunity testing and improves antenna sensitivity to low level signals. During emissions testing the measured field strength can be calculated by adding the antenna factor for the particular frequency to voltage measured at the antenna output terminal.
