Description
The TC-93060A Antenna Coupler supports wireless device testing up to 5.8 GHz. Engineers commonly use this coupler for radiated testing in RF shield boxes.
The TC-93060A uses Left Hand Circular Polarization (LHCP). This polarization works well for testing many wireless devices. However, when testing GPS or GNSS devices, the TC-93061A offers a better choice. The TC-93061A uses Right Hand Circular Polarization (RHCP), which matches GPS signal requirements.
This antenna coupler combines the small size of a standard inductive coupler with added flexibility. It allows users to place the coupler farther from the device under test. As a result, engineers can test the full wireless device assembly, including the antenna.
Users install the antenna coupler with a mounting fixture. They attach it to the ceiling of the TC-5972D or TC-5970D RF shield box. This setup supports reliable and repeatable wireless testing. For GPS and GNSS applications, engineers should select the TC-93061A Antenna Coupler for best performance.
Understanding Circular Polarization
RHCP antennas use Right Hand Circular Polarization. LHCP antennas use Left Hand Circular Polarization. Engineers often refer to both as Circular Polarized (CP) antennas.
Circular polarization helps reduce radio interference caused by signal reflections. This effect, known as multipathing, blocks unwanted signals and improves signal clarity. Because of this benefit, circular polarized antennas work especially well for radiated testing inside an RF shield box, also known as a Faraday cage.
