R&S Presents Conformance Testing Solution for 5G NR FR2
Columbia, MD — Rohde & Schwarz (R&S) is now offering a 5G confor- mance testing solution for both FR1 and FR2, which includes the latest version of the popular TS8980 RF test system, now covering 5G NR. To enable over-the-air (OTA) testing, the solution includes the new ATS1800C compact antenna test range (CATR) based 5G NR mmWave test chamber. The introduction of the new,
mmWave-based FR2 frequency range for 5G and the increased use of active antennas without physical connectors requires testing to be performed over the air. R&S has developed a test solution able to perform tests for RF conformance in 3GPP FR2. The device under test, a 5G smartphone, is placed in the ATS1800C chamber. The chamber is also available in a special configuration for extreme temperature testing in 3D. The R&S TS8980 is a well-estab-
lished family of RF conformance test systems. With the addition of the new CMX500 radio communication tester, the RF conformance system gains 5G NR signaling functionality. The upgraded R&S TS8980FTA
is, reportedly, the only RF confor- mance test system in the market that supports mobile technologies all the way from 2G to 5G on one platform. A special feature of the R&S TS8980 - FTA is the smooth upgrade path to 5G. Users who already have the previ- ous version of the R&S TS8980 can upgrade to 5G RF FR1 testing by adding the R&S CMX500 as an exten- sion box. While in FR1 all the tests are done in conducted mode, the need in FR2 is to test over-the-air. This is made possible by extending the
Skyworks Launches Frontend Modules for Wi-Fi 6
Irvine, CA — Skyworks has intro- duced its SKY85333-11 (2.4 GHz) and SKY85747-11 (5 GHz), two new frontend modules (FEMs) to its port- folio of solutions designed for high- power Wi-Fi 6 (802.11ax) applica- tions and systems. These highly integrated FEMs
incorporate a switching, low-noise amplifier (LNA) with bypass and a power amplifier (PA) for devices that include networking and WLAN- enabled wireless streaming systems. Both devices offer a very low
EVM floor with a 1024-QAM signal, which improves throughput and meets requirements for MU-MIMO operation. The modules offer extre - mely high linear output power — up to regulation limits for improving coverage range. The SKY85333-11 and SKY85747-11 are available in a compact 24-pin, 0.1 x 0.2 in. (3 x 5 mm) LGA package and support lead-
ing reference designs. Contact: Skyworks Solutions,

TS8980FTA with a very compact CATR system. A CATR testing solution includes
a reflector to minimize the space requirements for OTA tests. For the 5G frequency range FR2 user equip- ment conformance test, CATR designs are the best practical choice, since the required plane wave signals are avail- able in distances measured in decime- ters from the reflector, instead of meters as in direct far field chambers. A CATR setup is reciprocal and can be used for the transmission characteris- tics of the device, as well as the receiv-
er characteristics. The setup includes the new
CATR-based R&S ATS1800C for FR2 testing. The solution includes a gold-
coated reflector with a large quiet zone of 11.8 in. (300 mm), fulfilling 3GPP 5G NR conformance test requirements. Completing the test setup is a configuration for extreme temperature testing. With a frequen- cy range 18 to 90 GHz, the solutions have potential applications well
beyond the current FR2 bands. Contact: Rohde & Schwarz USA,
