SDR-LW 2974-24/44 is a product developed by Wuhan Luoguang Electronics based on the classic radio equipment SDR-LW 2974. The transmit and receive frequency is increased to 24GHz/44GHz, while inheriting all the functions and advantages of the former. Like all USRP devices, this device adopts open-source cross-platform UHD driver and supports most applications and SDR frameworks, such as GNU Radio, Matlab, LabView.
