The TEM3000 from Montena Technology is a TEM Cell with a frequency range from DC to 3 GHz. It has a septum height of 25 mm and a usable test area under the septum of 110 x 71 mm. This cell can handle an input power of up to 400 W and a field intensity of 5.6 kV/m. It is ideal for the immunity testing of small objects (such as watches, telephones, or PCBs) according to European (CE) and automotive standards (SAE J1113-25) or for biological experiments. This TEM can also be used to calibrate field probes as the field inside the TEM cell is known with high precision. It has an open structure, which allows easy access to control the device under test (DUT). It has an input return loss of more than 10 dB (up to 3 GHz), more than 14 dB (up to 2 GHz) and more than 20 dB (up to 1 GHz) . This cell has a cell impedance of 50 ohms and a wave impedance of 377 ohms. It is available in an enclosure that measures 40.0 x 18.0 x 6.0 cm with N-type connectors and weighs 1.5 kg.
