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.
Key words : ultra wide band,;miniaturized;smaller package,;lightweight;phase-locked loop frequency synthesizer

頻率合成器是超外差體制通信偵察系統(tǒng)中必不可少的重要組成部分,,其主要實現(xiàn)以下兩方面功能:一為混頻時提供混頻器所需的寬帶本振信號,;另外為在系統(tǒng)測向功能前多通道校準時,利用標校源產(chǎn)生的寬帶標校信號對通道幅度與相位提供校準信號,,以實現(xiàn)精準測向[1],。超寬帶、小型化,、輕量化頻率合成器在現(xiàn)在通信偵察系統(tǒng),,尤其是便攜式通察系統(tǒng)中必不可少,得到了廣泛應(yīng)用并對其提出了更高的要求[2-3],。在通常超寬帶頻率合成器設(shè)計方案中,,通過多次混頻以達到頻率擴展的實現(xiàn)方案得到了廣泛應(yīng)用,但該方案由于使用混頻器,、濾波器和多級本振使功耗增加,、體積增大、重量無法降低,,不適用于便攜式系統(tǒng)中,。故本文提出一種單環(huán)模式,通過鎖定高頻寬帶壓控振蕩器后,,通過可編程分頻器實現(xiàn)頻率擴展,,采用先進的3D微封裝技術(shù),最終實現(xiàn)超寬帶微封小型化頻率合成器的設(shè)計[4-5],。
