With the rapid development of technologies in satellite communication, phased array radar, internet of things and other fields, high-frequency, multi-channel and high-performance radio frequency signal processing technologies have become increasingly important. The Ku-band, with its high spectrum resource utilization and relatively controllable transmission loss, has become the core frequency band used in space-air-ground integrated communication networks and high-precision radar systems. However, single-channel RF technology is no longer sufficient to meet the concurrent communication demands. Against the backdrop, the research on multi-channel Ku-band RF signal transmission and reception processing technology holds theoretical significance and engineering application value for enhancing the capacity and anti-interference ability of communication systems.
