| Zusammenfassung: | The accurate measurement of Passive intermodulation (PIM) generated from RF radiating components requires an interference-free environment. The anechoic chamber environment is a suitable option to avoid any external interference that may disturb the PIM measurement. However, RF absorbers in anechoic chambers can be a potential source of PIM and thus affect the measurement accuracy. This paper presents a detailed evaluation of PIM performance for five kinds of absorbers from different manufacturers. It is confirmed that some RF absorbers can be a potential source of PIM. The obtained results show that the conductive carbon material used in fabricating the WAVASORB® VHP-8 absorber, EHP- 5PCL absorber and MWA-LFA produces low level of PIM. The nano-metal films incorporated inside Frankonia absorber produces lower PIM compared to carbon-made absorbers. Lastly, the absorber made from EVU material (dry mix of cellulose materials, carbon fibers and other components) produces a higher PIM level. |
