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.
