TDK RF Solutions
The TDK semi-anechoic EMC chamber CAC-S™, with a size of 7.5 m long, 4.0 m wide and 3.0 m high (24'-7" x 13'-1" x 9'-10"), is the most compact EMC anechoic test facility to perform radiated EMC measurements between 26 MHz and 18 GHz. A major advantage of this RF anechoic chamber is that it can be constructed within most industrial buildings and office areas.

The space saving characteristics are obtained by the use of a particular EMC absorber installation technique which was invented and patented by TDK - the double layer technique. TDK ferrite tiles are mounted onto dielectric panels to cover the complete frequency range from 26 MHz to 1,000 MHz.
By installing TDK IP-045 series resistive absorbers in selected areas of ceiling and walls, the frequency range can be extended up to 18 GHz. White end caps complete the absorbers and greatly improve the illumination levels inside the EMC anechoic chamber.
CAC-S enables the user to carry out radiated immunity measurements in full compliance with IEC 1000-4-2 standard over the frequency range from 26 MHz to 18 GHz. 3 meter radiated emissions measurements can be performed at a fixed receive antenna height in the 30 MHz to 18 GHz frequency range. This makes the compact anechoic chamber (CAC-S) an ideal facility to test small apparatus.
Example of actual field uniformity results in a TDK compact semi-anechoic chamber CAC-S™ (measured by ARC Seibersdorf).
