ADRF6807 - 700 MHz至1,050 MHz正交解调器，集成小数N分频PLL和VCO - IQ解调器 - 射频和微波 - Analog Devices, LLC
ADRF6807是一款高动态范围IQ解调器，集成锁相环(PLL)和电压控制振荡器(VCO)。小数N分频PLL/频率合成器产生2.8 GHz至4.2 GHz范围的频率。可编程正交分频器（分频比 = 4）将VCO输出频率分频至所需的本振(LO)频率，以便以正交方式驱动混频器。此外，输出分频器（分频比 = 4至8）产生一个分频VCO信号供外部使用。
PLL支持9 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。
IQ解调器将差分RF输入与源自正交分频器的复数LO混频。差分I和Q输出路径具有出色的正交精度，可以处理基带信号或最高120 MHz的复数中频信号。
通过对串行接口寄存器编程以降低功耗，还可提供低功耗工作模式，同时输入线性度和输出驱动电流略有降低。
ADRF6807采用先进的硅锗BiCMOS工艺制造，提供40引脚、裸露焊盘、符合RoHS标准的6 mm x 6 mm LFCSP封装。额定温度范围为-40°C至+85°C。
应用
The ADRF6807-EVALZ is a full featured evaluation board designed to allow the user to easily evaluate all features of the ADRF6807. The evaluation board provides a USB interface for easy VCO frequency programming. RF input and baseband output SMA connections with single ended setups are featured. There is an option of fully differential baseband signaling on the output at the card edge if user desires. Access to the +3.3 V/208 mA supply and +5 V/86 mA supply is achieved with clip leads to the VCC2 and GND2 testpoints and the VCC and GND testpoints respectively; the supplies have a range of +3.135 V to +3.465 V and +4.75 V to +5.25 V, respectively. The ADRF6807-EVALZ board is a 4 layer board made of Rogers material. Setting the VCO frequency (and other functions) is achieved via the SPI port which can be programmed via the ADRF6807 USB software provided on the ADI webpage.
