Abstract

The EMC - Electromagnetic Compatibility for Electronic Equipment is a critical task in several sectors in the industrial environment. Different approaches support the compliance tests and have consolidated standard and regulations. In many cases, integrated circuits are the mainly causes of interference in electronics equipments. In this work it is shown the concept and models for matching the APEX (exciter) and the GTEM chamber, which is the most important and critical step on the construction of the system and its optimization. Also, it is shown the basic concepts to design this versatile chamber, projected to operate from 500 MHz - 18 GHz, employed in pre-compliance tests and electromagnetic compatibility for automotive/electronic boards and integrated circuits. The GTEM chamber has some advantages over the others test setups, mainly in economic terms and the operational frequency range.
