SE129 Series Antenna

The SE129 Series interferometer antenna array consists of three antenna sub-arrays and their respective radomes integrated with an RS-422 controlled radio frequency (RF) module. Operation is from 0.5-18 gigahertz, with the above mentioned antenna sub-array covering 0.5-2, 2-6, and 6-18 gigahertz. Customized cavity-backed spiral antenna apertures provide for wide-angle coverage. The integrated RF module provides preamplification, filtering and RF-switching allowing for direct interface of the SE129 with customer furnished receivers. The RF-switching network allows selection of the antenna sub-bands or a calibration path. The radomes, which are integrated into the panel are designed for minimal insertion loss and phase error, provide protection from the flight environment. This allows the SE129 to operate without need for any additional radomes or aerodynamic fairings. The SE129 Series has been designed to meet the stringent requirements of today’s manned and unmanned military platforms.
