Introduction
The document discusses the challenges posed by the increasingly perturbed electromagnetic environment due to the evolution of wireless technologies. It introduces SIEPEL's solution: a high-quality shielded and anechoic cabinet designed for R&D and testing of small RF and microwave products in such environments.

Main Features
The shielded anechoic cabinet is suitable for small RF/microwave devices and antennas. It has external dimensions of 900 x 600 x 600 mm, with custom designs available. The cabinet features a knife-edge shielded door providing high shielding effectiveness (120 dB @ 1 GHz) and is internally lined with high-performance absorbers. It includes various feedthrough options such as power supply, RF connectors, and fibre optics, and is designed to be upgradeable, flexible, ruggedized for lab life, easily movable, and space-saving.

Construction and Technology
The cabinet is constructed using modular sandwich shielding panels, similar to those used in SIEPEL's shielded rooms and anechoic chambers. The door utilizes knife-edge technology with a patented brass knife and copper-beryllium fingerstock.

Absorbers Lining
The cabinet can be lined with electromagnetic absorbers to ensure a stable EM environment and high measurement repeatability. Options include ferrite tiles absorbers (30 MHz – 1 GHz), broadband pyramidal absorbers (800 MHz – 18 GHz), and resonant tuned silicone absorbers.

Feedthrough Options
The cabinet can be equipped with various feedthrough options, including brass framed panels with RF connectors, fibre optics waveguides, honeycomb air vents, power filters, control line filters, and USB/Ethernet/RS232 fibre optics converters.
