| 摘 要： | 介绍了一种新型的高性能雷达频率综合器的制作方法，即采用声表面波技术制作高性能的雷达频综器。采用这种方法成功地制造了Ｌ波段、Ｓ波段、Ｃ波段超低相位噪声超高速频率综合器。该类频综输出信号具有极低相位噪声（１．６ＧＨｚ处：单边带相位噪声Ｌｍ（１ｋＨｚ）＝－１２７ｄＢｃ／Ｈｚ；３．４ＧＨｚ处：Ｌｍ（１ｋＨｚ＝－１２２ｄＢｃ／Ｈｚ；６．８ＧＨｚ处：Ｌｍ（１ｋＨｚ）＝－１１６ｄＢｃ（Ｈｚ）、极短的频率切换时间（约１６０ｎｓ）、低杂波电平（Ｌ波段为－７０ｄＢ；Ｓ波段为－６５ｄＢ；Ｃ波段为－６０ｄＢ）、较多频点（５１点）等多项优异性能。同时，该频综通过了各项环境试验的考核，且长期工作性能稳定。

| Abstract: | Novel radar frequency synthesizers with high performance have been fabricated through SAW technology, by which extreme low phase noise, ultra high speed frequency synthesizers in L,S, and C band have been successfully made. These synthesizers are featured with extreme low phase noise (single side band phase noise L m(1 kHz)=-127 dBc/Hz at 1.6 GH; L m(1 kHz)=-122 dBc/Hz at 3.4 GH; L m(1 kHz)=-116 dBc/Hz at 6.8 GHz), extreme short time for frequency switching (about 160 ns),low spurious level(-70 dB,-65 dB,and -60 dB for L,S and C band respectively),and comparatively more frequency channels(51 channels). These synthesizers have passed various environmental tests and shown long term work stability. |
