GTEMkameroita

GTEMkameroita refers to a series of specialized electromagnetic interference (EMI) and electromagnetic compatibility (EMC) test chambers designed for performing radiated emission and immunity measurements. These chambers are a variation of the Gigahertz Transverse Electromagnetic Mode (GTEM) cell technology, which provides a controlled environment for RF testing. The "kameroita" suffix is Finnish for "chambers," indicating a likely origin or significant use within Finland.

The fundamental principle behind a GTEM chamber is to create a uniform electromagnetic field within its working volume. This is achieved through a specific geometric design, typically a tapered coaxial transmission line structure. The working volume is located at the wider end of the taper, where a high-quality, planar electromagnetic field is established. This allows for the testing of devices under test (DUTs) in a manner that simulates free-space conditions with a high degree of repeatability.

GTEMkameroita are utilized across various industries, including automotive, aerospace, telecommunications, and consumer electronics. They are essential for ensuring that electronic devices comply with international EMC regulations and standards. The chambers can accommodate a wide range of DUT sizes and are capable of performing tests across a broad frequency spectrum. Their compact size compared to traditional anechoic chambers and their ability to generate both electric and magnetic fields make them a versatile tool for EMC engineers.
