As the development and variety of the military requirements, the phased array radar technologies progress towards the characteristics with ultra-wideband, multiple-function, high performance and high integration. The microwave technologies, playing a basic role in phased array radar, also demand continuous development. In this paper, the relation- ship between microwave techniques and phased array radar is addressed firstly. Then the typical applications of recent micro- wave technologies in modern phased array radar are presented. The aspects include the new phased array antennas, the novel TR modules, the high performance solid state transmitters, the high-integrated feeding networks, the RF stealth techniques, the microwave photonics and so on. At last, the application potential and development trend of the microwave techniques in phased array radar is analyzed.
