Digital RF Technologies for Q/V-Band LEO SATCOM Constellation

Low Earth Orbit constellation Satellite Communication (LEO-SATCOM) is one of the non-terrestrial networks, and the development of the Q/V band is urgently desired. The next-generation LEO constellation requires flexible beam generation, and one key technology is full digital beamforming using a direct digital RF front-end. This talk presents a next-generation antenna that utilizes QV band direct digital technology, employing a high-order Nyquist zone to configure a compact RF front-end.
