TC5910DU RF Shield Box

Description

The TESCOM TC5910DU RF Shield Box is the upgraded version of the popular TC5910D. It delivers reliable RF shielding up to 12 GHz. As a result, it supports higher-frequency wireless testing requirements.

In addition, the TC5910DU retains the core features that engineers value in the TC5910D. However, it now offers improved shielding performance to meet modern wireless technology demands. Because of this upgrade, it works well for advanced RF and OTA testing applications.

Designed for Over-the-Air (OTA) Testing

The TC5910DU functions as a Faraday cage designed specifically for OTA testing. All interior walls include highly absorbent RF absorber material. Moreover, a layer of ferrite absorber helps reduce low-frequency reflections.

Because of this layered absorber design, the chamber minimizes reflections and multipath effects. Therefore, engineers can perform more accurate and repeatable OTA measurements. This controlled environment improves confidence in test results.

Flexible Test Configuration Options

To further enhance testing capability, users can add grid fixtures and antenna couplers. These accessories transform the TC5910DU into a complete OTA test solution. As a result, engineers can test handheld devices and other DUTs with consistent positioning.

Additionally, this flexible setup supports a wide range of device sizes and antenna types. Because of this adaptability, the shield box works well in both development labs and production environments.

How OTA Testing Is Performed

During OTA testing, engineers place the Device Under Test (DUT) inside the RF shield box. The chamber isolates the DUT from external RF interference. At the same time, the absorber-lined walls and antenna coupler reduce internal reflections.

The goal of OTA testing is to evaluate wireless performance in real-world conditions. However, many factors can affect results, including multipath reflections and outside interference. Because of these challenges, a controlled RF environment becomes essential.

By combining the TC5910DU RF Shield Box with an antenna coupler and fixture, engineers achieve better repeatability and measurement integrity. As a result, teams can validate device performance with greater confidence.
