Overview

The UME-28TR64DP128 has 4 antenna sub arrays, each containing 32 antenna units arranged in a 4×8 manner. Each subarray has 16 TR channels (including phase shifter, LAN, PA, and TR switching), and each TR channel is connected to 2 antenna units. 4 sub arrays can work independently and construct independent 4 beams from 32 antennas. The 4 sub arrays can also work together to construct a single beam with 128 antennas. The 28TR64DP128 integrates 4 bi-directional up/down converters, which can expand any IF device from 2 to 3.8 GHz to the 28GHz.

Each sub array built into 28TR64DP128 can achieve high-performance dynamic beam scanning in a total of 4096 states within a horizontal+/-60 ° and vertical+/-30 ° range. The sub array EIRP is 51dbm, and when used with 4 sub arrays in combination mode, the EIRP is as high as 59dBm, with an EVM as low as 2%. It can support QAM256 or high-order modulation and achieve rapid development of millimeter wave communication systems.

As a 4-channel millimeter wave phased array, the 28TR64DP128 can be used in conjunction with most SDR platforms on the market to extend Sub6G SDR devices to the millimeter wave frequency band. For example, the USRP X410 with a bandwidth of 400MHz and frequency coverage of 1M-7.2GHz can achieve millimeter wave four beam transmission and reception through a single 28TR64DP128.
