 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  made with  51 cm truncated pyramidal carbon-foam absorbers  HPT (RAM).
  •  GTEM-1250   made with  65cm pyramidal carbon-foam absorbers HPP (RAM).
