Design of ultrawideband and micropackaging frequency synthesizer

Abstract： In the modern electronic reconnaissance system, especially the portable and individual communication reconnaissance system, on the premise of ensuring the function and technical indexes stay the same, the volume and weight of the overall system are put forward higher requirements, the internal devices are required to have smaller volume and lighter weight. Therefore, realizing the miniaturized and lightweight ultra wide band frequency synthesizer has become the key point to realize portable reconnaissance equipment. Based on the single phase-locked loop(PLL) technique, this paper adopts a new circuit and process realization method to get the high performance ultra wide band frequency synthesizer, which provides a high performance, miniaturized and lightweight frequency synthesizer for engineering application.
