RF Chambers | RF Absorbers | Anechoic Chambers | DMCRF


 

In a world increasingly driven by wireless communication, the ability to test electronic devices in a
controlled and interference-free environment is critical. Whether it’s for smartphones, radar systems,
medical electronics, or automotive sensors, ensuring electromagnetic compatibility (EMC) and
performance requires precision. That’s where RF Chambers play a vital role.
At DMC RF, we design and manufacture high-performance RF Chambers equipped with cutting-edge
RF absorbers, offering unmatched accuracy in RF and EMC testing across industries.

What is an RF Chamber?

An RF Chamber (Radio Frequency Chamber) is a shielded enclosure designed to isolate devices from
external electromagnetic interference and contain internal emissions. It provides a stable, noise-free
environment for performing RF measurements, wireless device testing, antenna calibration, and
certification.
When paired with RF absorbers, these chambers are transformed into echo-free environments that
allow engineers to simulate real-world conditions and accurately test device performance.

The Role of RF Absorbers in RF Chambers

RF absorbers are materials that absorb electromagnetic energy rather than reflecting it. These are
installed on the interior surfaces of RF Chambers to:
Minimize internal signal reflections
Reduce standing waves
Improve measurement accuracy
Support wide frequency ranges
At DMC RF, our chambers feature high-quality RF absorbers made from advanced dielectric or
magnetic materials, designed to operate across a broad spectrum—from MHz to GHz.


Types of RF Chambers Offered by DMC RF
At DMC RF, we offer a variety of RF chamber types, each customized with RF absorber configurations
based on application:

Anechoic Chambers
Fully lined with pyramidal RF absorbers to eliminate reflections. Ideal for antenna and radar testing,
wireless device R&D, and advanced EMC analysis.

Shielded Rooms with Absorber Panels
Combines shielding effectiveness with flat absorber panels to support pre-compliance testing,
product design verification, and high-frequency testing.

Modular RF Chambers
Flexible chambers that can be relocated or resized. Available with optional RF absorber kits for
targeted testing scenarios.

Faraday Cage Chambers
Basic shielding structure that can be upgraded with internal RF absorbers for improved signal
absorption and precision.

Benefits of DMC RF Chambers with RF Absorbers

Enhanced Accuracy:
Absorbers reduce signal distortion and improve repeatability in tests.
Wide Frequency Range Coverage:
From MHz to millimeter-wave bands—ideal for current and future technologies like 5G and IoT.
Custom Configuration:
We design absorber layouts and chamber sizes to match your specific frequency, space, and
application requirements.
Durable, Fire-Retardant Materials:
Our RF absorbers are made to last, resist humidity, and meet global safety standards.
Compliance Ready:
Compatible with standards like FCC Part 15, MIL-STD-461, CISPR 11/22, ISO 17025, and IEC 61000.

Industries We Serve

DMC RF Chambers with absorbers are trusted by leading organizations in:
Telecommunications
Defense and Aerospace
