| Abstract: | Frequency synthesizer design topology of the airborne fire control radar is summarized, with the focus on the integrated PLL based broadband, and high reliable practical frequency synthesizer. Phase noise specification, bandwidth, and frequency agile time of the synthesizer are analyzed in depth, and the design idea and circuit implement topology of the synthesizer are described in details, where the qhase noise specification is similar to PLL synthesizer and the frequency hopping time is similar to direct synthesizer. The synthesizer has the advantages of broad bandwidth, frequency agile, and low phase noise, which can be used in miniaturized radar and signal simulator systems. |
