Anechoic Chamber
|
Anechoic Chamber Description we provide Semi-EMC Chamber and Full EMC Chamber for EMC Testing.
An Anechoic Chamber generally consists of an RF shielded room which is either partially or fully lined with RF absorber material. It is used to perform several types of testing and measurements.
our chambers are typically constructed from the modular shielding system.
EMC anechoic test chambers are used by industry to perform radiated emissions and radiated immunity testing of electrical/electronic equipment to various International specifications such as EN 50147 part 2 / ANSI C63.4 / EN55022 / EN61000-4-3 and various CISPR documents.
Chambers are also designed for EMC testing for testing in accordance with military and avionics specifications such as MIL STD 4612E, DO 160 and DEF STD 59-41.
we offers a fully range of anechoic chambers, including: Antenna EMC Testing Chamber |

Modular Anechoic Shielding for Accurate EMC Testing
The Haozhuo High Performance EMC Testing Chamber – RF Shielding Room 40 GHz employs a modular shielding system constructed from galvanized steel panels (2 mm/3 mm thick) for robust electromagnetic shielding. Lined partially or fully with RF absorber materials, it functions as an anechoic chamber to support both semi-EMC and full-EMC testing. Designed for evaluating radiated emissions and immunity across industry standards such as EN 50147‑2, ANSI C63.4, EN55022, EN61000‑4‑3, and various CISPR protocols, it also accommodates rigorous military and avionics test regimes including MIL‑STD‑4612E, DO‑160, and DEF STD 59‑41.
Precise Performance Across an Ultra-Wide Frequency Range
This chamber delivers shielding effectiveness exceeding 100 dB from 14 kHz to 40 GHz, ensuring exceptional suppression of external interference, including radio interference and microwave noise. For magnetic fields, it achieves up to 110 dB at 200 kHz, and for plane waves, up to 120 dB in the 50–103 MHz range—while maintaining strong attenuation into the microwave band (1–10 GHz: 110 dB; 10–20 GHz: 100 dB; 20–40 GHz: 80 dB). Such performance makes it invaluable for rf shield box manufacturers and EMI evaluation applications.
Adaptable Sizes and Reliable Production Capacity
Available in sizes ranging from compact chambers to 3‑m, 5‑m, and 10‑m free-space configurations, the chamber accommodates diverse facility layouts. Constructed with modular components, it supports customization and scalability. Delivery is made in wooden cartons, with a typical lead time of 3–5 weeks, aligning with industrial timelines. The inclusion of power filters, honeycomb vents, RF doors, and integrated absorber configurations ensures broad utility while preserving EMI reliability.
