Narda-MITEQ的(de)(de)SLS2系(xi)列(lie)(lie)鎖(suo)相頻率合成(cheng)器是(shi)針對L、S、C和(he)ku波段的(de)(de)低成(cheng)本替代(dai)方案,具備極(ji)低相位噪聲。這一系(xi)列(lie)(lie)合成(cheng)器在(zai)所有波段上均提供標準的(de)(de)1 kHz步(bu)進(jin)輸出(chu),是(shi)雙轉換上下(xia)變頻器的(de)(de)理想選(xuan)擇。SLS2系(xi)列(lie)(lie)具備+13 dBm的(de)(de)輸出(chu)功率和(he)60 dBc的(de)(de)雜散抑制,適用于最嚴格(ge)的(de)(de)系(xi)統應用。此(ci)外,該合成(cheng)器在(zai)(+7到(dao)28 V)直流電源下(xia)的(de)(de)功耗(hao)不(bu)超過4W。
關鍵特性:
降低成本投入> 10 dB不高于INTELSAT相位嘈音掩模>適宜于雙準換上、下變頻器> 1khz標準單位步長>可在八度寬頻段自帶摘引快速清理或外部摘引低G遲鈍度選項:
>自設定頻段>自的定義步長>高輸入電率界面
