Design of RF Module Suitable for AESA Jamming Smart Skin

Smart skin as an ultra-thin antenna system shaping with the install base surface, embedded by devices such as micro-unit of TX and transmitter linked with, receiver, beam former and so on, has super features in electronic and structure when used in radar, electronic warfare and communication system. It is considered as an attractive idea to settle the installation problems on air platform with traditional antenna feed system. An ultra-thin four-stage wideband radio frequency TX microcircuit power module that can be digital phase shifted is designed in accordance with the requirement of the smart skin active electronically scanned array jamming searching system architecture composed of synchronous clock tree and digital phase shift power TX modules. Some super convention methods such as high density digital鄄analog hybrid printed circuit board layout, sandwich structure for electromagneticcompatibility and electrical-structural integrated design are involved. Test results show that the designing scheme for smart skin is reasonable and feasible.
