Overview

UME-28UD is a 28GHz mmWave up and down converter that extends IF(2~3.8GHz) device to FR2 n257 band in TDD mode. UME-28UD can be controlled through USB-to-serial cable or high-speed differential SPI (HDMI connector) digital I/O connection. The RF range of UME-28UD is 27.2~29GHz, the IF range is 2GHz~3.8GHz, and the LO frequency range is 25.2GHz. It can extend the sub 6G devices such as NI PXIE-5841 and USRP-2954 to the FR2 n257 band.

Highlights

• Ultra-compact handheld design, with integrated array antenna.
