Description
TC-93023B Antenna Coupler Overview
The TC-93023B antenna coupler supports near-field RF testing for wireless devices operating up to 2.4 GHz. Engineers use this coupler inside RF shield boxes to achieve stable and repeatable measurements while limiting outside interference. Because the coupler operates across 800 MHz to 2650 MHz, it supports many common wireless technologies used today.
This model is often selected when teams need reliable coupling without direct electrical contact. As a result, device antennas perform naturally during testing, which improves measurement accuracy.
Near-Field RF Coupling Performance
This antenna coupler delivers controlled signal coupling in near-field environments. Instead of forcing a hard connection, it allows radiated testing that better reflects real-world operation. Consequently, engineers can evaluate device performance more accurately.
Near-field testing environments often suffer from reflections and multipath effects. However, this coupler helps maintain consistency between test cycles. That consistency reduces false failures and improves overall confidence in test results.
Frequency Coverage and Typical Applications
Operating from 800 MHz to 2650 MHz, this antenna coupler supports several common use cases, including:
-
Wi-Fi and Bluetooth validation
-
IoT and consumer electronics testing
-
Embedded wireless module evaluation
-
Pre-compliance RF measurements
Because of this wide coverage, the coupler works well in both development and production environments.
Use Inside RF Shielded Enclosures
Engineers typically install this antenna coupler inside an RF shield box or Faraday cage. This setup isolates the device under test from external signals. As a result, measurements remain clean and repeatable.
To ensure consistent positioning, teams often pair the coupler with a mounting fixture. This approach helps maintain reliable test geometry from device to device.
Solutions like this are commonly used alongside RF test systems from TESCOM.
