GTS-RP Systems

Wireless terminal certification level supports 5G FR2 OTA test system

Product Description

GTS Solutions has broken through the traditional design of the reflector and feed system. The key indicator of quiet zone quality has been improved by 50% compared to traditional systems, and the measurable range is as high as 70% of the reflector area. The overall design of the measurement and control software, test instruments, links, and mechanical turntable enables collaborative operation, increasing testing efficiency by up to 60% compared to traditional dark rooms. The fusion design of absorbing materials, reflectors, feeds, and microwave darkrooms makes the new generation of compact ranges compact in internal structure, small in size, and easy to transport and install. The system is validated for quiet zone and dark room calibration before leaving the factory, and can be delivered and used immediately upon arrival at the customer site. The system turntable and link interfaces are open, allowing users to customize test cases to meet various millimeter wave testing needs. An efficient technical team provides 24/7 technical support domestically and internationally, and high-quality remote and on-site technical services ensure the smooth operation of the system, relieving customers of any worries.

Features

Phase Centered Feeds

GTS has designed a wideband corrugated horn feed with low cross-polarization for angle measurements. The E-plane and H-plane phase center fluctuations are less than 5°, cross-polarization is less than -30dB in the 24-40GHz frequency range, and antenna standing wave ratio is less than 1.5.

Reflective surface with low edge scattering

Universal Test ingeniously integrates the reflective surface and the inner wall of the absorbing material of the box by nesting the absorbing edge outside the reflective surface, greatly reducing the influence of edge scattering of the reflective surface, increasing the proportion of the quiet zone, and improving the quality of the quiet zone.

High-precision, low-occlusion turntable for fast sampling

The Tight Field series is equipped with a multi-dimensional turntable that can move in azimuth, polarization, elevation, and translation according to user needs. To address the challenges of narrow beamwidth, long testing time, and turntable blocking commonly encountered in millimeter wave testing, General Test has improved and designed a high-precision, fast-sampling, low-blocking multi-dimensional turntable suitable for millimeter wave measurement.

Customized high-performance absorbing materials

The compact range system undergoes static zone verification, system pre-assembly, and debugging before delivery, allowing for quick installation and immediate use without the need for on-site adjustments. Each precision component in the system is carefully designed and arranged to optimize the use of space and minimize free space attenuation, addressing the challenges of large path loss in millimeter-wave testing. Moreover, the system provides ample upgrade space, including flexible fixture configurations and redundant link design, to meet the diverse testing needs of different DUTs.
