TEM Cells

The IFI CC Series of TEM Cells offer the necessary environment for performing pre-compliance and compliance testing in a package that is convenient, cost-effective and (in certain respects) technically superior to the larger anechoic chamber. The CC TEM Cells consist of a rectangular transmission line operating in the transverse electromagnetic mode (TEM). The cell is tapered at each end to a transition section that includes type N coaxial jacks for signal connection. Size and precision design of the CC series allow for accurate maintenance and measurement of E-Field levels (within ± 1.0 dB on most models) without antennas. The geometry of the cell combined with it's well maintained impedance minimizes undesirable resonance effects.

In addition, the typical VSWR is less than 1.25 to 1. To summarize, the ability to produce, maintain and measure E-fields is considerably easier within a CC Series TEM cell than within the larger anechoic chambers. The compact size of the CC Series allows them to be easily moved around, essentially acting as a "benchtop shielded room". And with IFI's line of amplifiers and accessory products, your whole test area can take up a fraction of the space of a standard EMC test facility.With the average CC TEM cell costing two to four percent of an average anechoic chamber, manufacturers could afford a complete test setup, and test labs can afford multiple test setups.
