Broadband Up/Downconverting Mixer with Integrated Fractional-N PLL and VCO

GENERAL DESCRIPTION The ADRF6655 is a high dynamic range active mixer with integrated PLL and VCO. The synthesizer uses a programmable integer-N/fractional-N PLL to generate a local oscillator input to the mixer. The PLL reference input is nominally 20 MHz. The reference input can be divided by

寬帶上/下變頻混頻器，集成小數(shù)N分頻PLL和VCO

ADRF6655是一款高動態(tài)范圍有源混頻器，集成PLL和VCO。頻率合成器利用可編程整數(shù)N分頻/小數(shù)N分頻PLL產(chǎn)生本振輸入，供給混頻器。PLL基準(zhǔn)輸入標(biāo)稱值為20 MHz?；鶞?zhǔn)輸入可以進行分頻或倍頻，然后施加于PLL鑒相器。PLL支持10 MHz至160 MHz范圍內(nèi)的輸入基準(zhǔn)頻率。鑒相器輸出控制一個電荷泵，其輸出在片外環(huán)路濾波器中進行積分。然后，環(huán)路濾波器輸出施加于一個集成式VCO。VCO輸出(2 × fLO)再施加于一個本振(LO)分頻器和一個可編程PLL分頻器。\n\n 可編程分頻器由一個Σ-Δ調(diào)制器(SDM)進行控制。SDM的模數(shù)可以在1至2047范圍內(nèi)編程。\n\n ? 集成小數(shù)N分頻PLL的寬帶有源混頻器 \n? 內(nèi)部LO頻率范圍：1050 MHz至2300 MHz \n? 輸入P1dB：12 dBm \n? 噪聲系數(shù)(單邊帶)：12 dB \n? 200 Ω輸出匹配阻抗 \n? 40引腳、6 mm × 6 mm LFCSP封裝\n\n;
