Phase shifters are critical elements for electronically scanned phased array antennas that allow the antenna beam to be steered in the desired direction without physically re-positioning the antenna. Electronic phase shifters assumed special significance because of their potential utility and volume requirement in phased array antenna systems for inertia less scanning.

CEL is one of the very few companies, worldwide, that have pioneered the production of the ferrite phase shifters for C- and X- bands. The ferrite phase shifter supplied by CEL is an indigenously developed product and CEL is totally self-reliant for various materials/components used in the design.

CEL has developed various production facilities for meeting the bulk demand of the phase shifters. The measurement of the phase shifter is fully automated using customized software

CEL can take up development work on ferrite phase shifters with customized specifications. Indigenous design hence can be customized as per the user requirement.

USP
