5G devices operating in the mmWave range (FR2), such as smartphones and tablets, require over-the-air (OTA) testing since these devices usually have no RF port or interface to connect to, and conducted tests are therefore not possible. At Mobile World Congress, Rohde & Schwarz is demonstrating new solutions to reliably and efficiently test large quantities of FR1 and FR2 devices. FR2 testing is based on the new R&S CMP200 radio communication tester in combination with the new R&S CMQ200 shielding cube. The FR1 sub 6 GHz test solution is implemented with the well-known R&S CMW100 radio communication tester running new measurement software.
R&S CMP200 + R&S CMQ200: Fully integrated OTA test solution for 5G FR2 devices
The R&S CMP200 radio communication tester combines a vector signal analyzer and an ARB generator functionality. The compact one-box solution can be customized with up to three R&S CMPHEAD30 remote radio heads (RRH) for up and down-converting signals to 5G FR2 frequencies.
The separate one-box tester and RRH concept allows short RF cable lengths for an optimal link budget in radiated test environments. This approach makes it possible to test fully assembled FR2 devices and RFICs that have both IF and mm-Wave RF interfaces. The multiband R&S CMPHEAD30 covers all relevant 5G bands including the 28 GHz and 39 GHz ranges.
The R&S CMQ200 is a compact, flexible 19" shielding solution that can accommodate most 5G devices in different applications. The drawer concept enables fully automated handling in manufacturing environments. Thanks to the robust mechanical design, the R&S CMQ200 withstands millions of test cycles.
With the R&S CMP200 and R&S CMQ200, Rohde & Schwarz offers its customers a fully integrated, single-source solution that delivers reliable, reproducible results for radiated measurements.
R&S CMW100: Conducted manufacturing test solution for 5G FR1 devices
At MWC 2019, R&S is also showcasing its well-known R&S CMW100 radio communication tester running the latest 5G analyzer and generator software personalities. In addition to 5G, the industry-leading solution supports all major cellular standards (3G, 4G) and wireless technologies (Bluetooth®, WLAN, etc.).
