Montena Technology - Open TEM Cells
- Test to international and automotive standards (IEC 61967-2, SAE J1113-25 J1752-3)
- Use in ordinary facilities. No Chamber required
- Test upt 3GHz (depending on Model)
These open TEM cells (tri-plate cells) are well suited for immunity testing of small objects according to international and automotive standards (IEC 61967-2, SAE J1113-25 J1752-3) or for biological experiments. The advantage of these TEM cells is that they are open. This enables an easy access to control the device under test. Applications are for instance the immunity testing of watches, phones or PCB's. In comparison with other closed TEM cells, the price is lower. The field rapidly decreases outside the open TEM cells (about 33 dB at 1 meter) which makes it possible to use an open TEM cell in ordinary facilities. Another interesting application is the calibration of field probes because the field inside the TEM cell is known with high precision. TEM cells are the most precise structures for field calibration.
