Ｘ波段雷达频率合成器完成了实用化Ｘ波段的综合样机，样机已通过环境试验要求。达到指标如下：工作频率范围为８．６～９．５ ＧＨｚ；本振输出功率≥１７．５ ｄＢｍ；本振输出相噪（１ｋＨｚ）≤－９０ｄＢ／Ｈｚ；本振输出谐波＜－５０ ｄＢｃ；本振输出杂散＜－６０ ｄＢ
X-band radar frequency synthesizer completed a practical X-band integrated prototype, the prototype has passed the environmental test requirements. Achieve the following indicators: Operating frequency range of 8.6 ~ 9.5 GHz; LO output power ≥ 17.5 dBm; LO output phase noise (1kHz) ≤-90dB / Hz; LO output harmonic <-50 dBc ; LO output spurious <-60 dB
