FE Module
R1028B: 28GHz, Dual-Polarized Planar Antenna Array
8x4/8x8 Dual-Polarized Planar Antenna Array
Detail
Overview

R1028B mmWave front-end module is developed for 5G mmWave high data rate transmission on 28GHz. It not only supports scalable antenna element and high-speed beam switching but also can provide horizontal/vertical (H/V) different beam resolution simultaneously. R1028B is also a commercial product to let user conduct transmission in mmWave band, or further, integrate any baseband chip to develop into 5G mmWave commercial products like 5G NR mmWave CPE and 5G NR mmWave Radio Unit (RU).
