GTEM-800F Datasheet

 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 750 family consist of  the:

GTEM-750  made with  65cm  pyramidal carbon-foam absorbers (RAM).

GTEM-800  made with  51cm EMC Truncated pyramidal absorbers (RAM).

GTEM-800F  made with  Ferrite tiles on the bottom and 45cm Hybrid pyramidal carbon-foam absorbers (RAM).
