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

宽带上/下变频混频器，集成小数N分频PLL和VCO

ADRF6655是一款高动态范围有源混频器，集成PLL和VCO。频率合成器利用可编程整数N分频/小数N分频PLL产生本振输入，供给混频器。PLL基准输入标称值为20 MHz。基准输入可以进行分频或倍频，然后施加于PLL鉴相器。PLL支持10 MHz至160 MHz范围内的输入基准频率。鉴相器输出控制一个电荷泵，其输出在片外环路滤波器中进行积分。然后，环路滤波器输出施加于一个集成式VCO。VCO输出(2 × fLO)再施加于一个本振(LO)分频器和一个可编程PLL分频器。\n\n 可编程分频器由一个Σ-Δ调制器(SDM)进行控制。SDM的模数可以在1至2047范围内编程。\n\n • 集成小数N分频PLL的宽带有源混频器 \n• 内部LO频率范围：1050 MHz至2300 MHz \n• 输入P1dB：12 dBm \n• 噪声系数(单边带)：12 dB \n• 200 Ω输出匹配阻抗 \n• 40引脚、6 mm × 6 mm LFCSP封装\n\n;
