Anritsu Company introduces its newly developed Butler Matrix 4×4 (0.6 GHz to 7.125 GHz) MA8114A to broaden Butler Matrix[*1] module lineup of simulating MIMO connections.

The MA8114A is a Butler Matrix transmission path with 4 enter and 4 output ports and helps the 6 GHz band (5.925 GHz to 7.125 GHz), which isn’t supported by the present Azimuth STACSIM-WB-(Static Channel Simulator) (ACC-339) used for evaluating 4×4 MIMO throughput of LTE/5G base stations and Wi-Fi units.

Growth Background

– Commercial –

LTE/5G Base station and Wi-Fi system distributors use the OTA*2 take a look at setting to judge the utmost throughput with 4×4 MIMO for his or her merchandise. This strategy has the issue of low reproducibility of measurement outcomes, nevertheless, as a result of the transmission setting varies relying on the space to the Person Tools (UE). Whereas bettering the reproducibility requires connecting the 2 units utilizing an RF cable, a easy coupler can not simulate the MIMO transmission setting. The MA8114A ensures extremely reproducible measurements.

The upper-limit frequency for NR FR1 has been prolonged starting with 3GPP Launch 17, and the 6 GHz band has been added to Wi-Fi 6E/7. The MA8114A helps a frequency vary as much as 7.125 GHz in preparation for nations launching providers on new frequency bands.

Anritsu helps prospects construct a steady 5G/Wi-Fi analysis setting and effectively take a look at throughput.

The product lineup of the Butler Matrix module additionally contains the Butler Matrix 8×8 (0.6 GHz to 7.125 GHz) MA8118A with 8 enter and eight output ports, which helps a frequency vary as much as 7.125 GHz as properly. The MA8118A can be utilized not just for 8×8 MIMO throughput analysis but additionally to allow environment friendly testing of units having a number of RF ports.

Technical Phrases

[*1]: Butler Matrix

A kind of microwave beamforming phased array proposed in 1958 by Judith Butler et al. with a number of enter and output ports to divide energy enter to 1 port equally to output ports at totally different phases.

[*2]: OTA

Abbreviation for Over The Air. Because the Tx/Rx radio efficiency of a wi-fi system is measured over the air, the usage of an OTA chamber, which is an anechoic chamber designed to dam exterior radio waves, is really helpful.
