GTEM 1250 - 1300

The GTEM cell is, in principle, a tapered coaxial line (offset septum plate), which is terminated by a hybrid combination of discrete resistors and RF absorber to achieve a 50 Ohm broadband match. It is applied for the measure of Radiated emissions and radiofrequency field-immunity tests. The GTEMCELL GTEM 1250 family consist of the: GTEM-1300 F made with Ferrite tiles on the bottom and 45cm Hybrid pyramidal carbon-foam absorbers (RAM). GTEM-1300 F-FR made with Ferrite tiles on the bottom and 45cm Hybrid pyramidal multilayer metal oxide film absorbers H450-B (RAM) . GTEM-1300 is made with 51 cm truncated pyramidal carbon-foam absorbers HPT (RAM). GTEM-1250 is made with 65cm pyramidal carbon-foam absorbers HPP (RAM).
