TEM Cells

TEM (Transverse Electromagnetic Mode) Cells are simple and efficient, needs low power for required field strengths.

Can only be used in a screened room

•Limited to small sizes

•Limited upper frequency

•15 x 15 x 5 cell: 500MHz

•30 x 30 x 10 cell: 200MHz

GTEM

Gigahertz TEM Cell

    Avoids limitations of TEM cell by taking the co-axial input feed and gradually expanding the section. Absorber on end wall prevents reflections. Co-axial core feeds septum plate which is offset to increase EUT volume. Very efficient. Needs low power input for required field strength. No power is absorbed until wavefront passes EUT and reaches end face.

    LaplaCells

    LaplaCells reach a performance level to match the GTEM.
    Field uniformity achieved with unique dual septum design.
    Balanced septum configuration… offers maximum EUT volume for given chamber size.
    RF Efficiency is high as GTEM.
