ADI公司的ADF4371是集成压控振荡器(VCO)的微波宽带合成器,其基本输出频率范围从4000MHz到800MHz,和外接大回路滤波器和外接基准频率一起,可产生62.5MHz到32GHz的输出频率,高分辨率39位分数模块,典型的杂散为-90dBc,集成的rms抖动为38 fs(1 kHz to 100 MHz),归一化相位噪声图为−234 dBc/Hz PFD@ 250 MHz,基准频率工作600MHz,可编分频器1,2,4,8,16, 32或64输出,模拟和数字电源3.3V,VCO电源3.3V和5V,主要用在无线基础设备(移动通信(MC-GSM)的多载波全球系统,5G),测试测量,航天与国防,时钟发生器.本文介绍了ADF4371主要特性,功能框图以及评估板EV-ADF4371SD2Z主要特性,建立图,电路图,材料清单和PCB设计图.

The ADF4371 allows implementation of fractional-N or Integer N phase-locked loop (PLL) frequency synthesizers when used with an external loop filter and an external reference frequency. The wideband microwave voltage controlled oscillator (VCO) design allows frequencies from 62.5 MHz to 32 GHz to be generated. The ADF4371 has an integrated VCO with a fundamental output frequency ranging from 4000 MHz to 8000 MHz. In addition, the VCO frequency is connected to divide by 1,2,4,8,16,32,or 64 circuits that allows the user to generate radio frequency (RF) output frequencies as low as 62.5 MHz at RF8x. A frequency multiplier at RF16x generates from 8 GHz to 16 GHz. A frequency quadrupler generates frequencies from 16 GHz to 32 GHz at RF32x. RFAUX8x duplicates the frequency range of RF8x or permits direct..
