IEC 61967-2 Chip Test Integrated Circuit Gigahertz Transverse Electro Magnetic Cell

Product Overview For Chip Test Integrated Circuit GTEM Cell:

GTEM (Gigahertz Transverse Electro Magnetic) Gigahertz Transverse Electromagnetic Wave Cell is a single-port closed waveguide with a frequency up to 20GHz.

Using GTEM (Gigahertz Transverse Electromagnetic Wave) for electromagnetic compatibility testing is a new measurement technology developed in the field of international electromagnetic compatibility in recent years. Due to GTEM's broadband characteristics (from direct current to microwave) and low cost (only a few percent of the cost of an anechoic chamber), it can be used for electromagnetic radiation susceptibility tests (EMS tests, sometimes called immunity tests). It can also be used for electromagnetic radiation test (EMI test) and the equipment used (compared to the test in the anechoic chamber) has simple configuration. The cost is cheap and it can be used for fast and automatic testing, so it has been paid more and more attention by relevant international and domestic people. Among them, especially for the testing of small equipment, the measurement solution of the GTEM cell is the best test solution with the best performance-price ratio.

Composition For Chip Test Integrated Circuit GTEM Cell:

GTEM can be regarded as a spatial expansion of the 50Ω coaxial cable in order to accommodate the measured object. The core wire of the coaxial cable is expanded to be the core plate of the GTEM cell, and the sheath of the coaxial cable is made into the shell of the GTEM cell. The characteristic impedance inside the GTEM cell is still designed to be 50Ω. In order to prevent the input electromagnetic wave from being reflected at the end of the internal cavity, the end of the core board is connected to a broadband matching load, and a wave-absorbing material is placed at the end of the cavity. In order to absorb the electromagnetic waves emitted to the end.

The transverse electromagnetic wave propagates along the core plate, and the electric field intensity generated is proportional to the voltage applied on the core plate. The strength of the field at different positions also depends on the height of the core board (the distance between the inner conductor and the ground), the closer to the partition, the stronger the field strength.
