产品详情

ADF4159是一款具有调制、以及快速和慢速波形产生能力的13 GHz小数N分频频率合成器, 该器件使用25位固定模数,提供次赫兹频率分辨率。

ADF4159由低噪声数字鉴频鉴相器(PFD)、精密电荷泵和可编程参考分频器组成。 该器件内置一个Σ-Δ型小数插值器,能够实现可编程小数N分频。 INT和FRAC寄存器可构成一个总N分频器(N = INT + (FRAC/225))。

ADF4159可用于实现频移键控(FSK)和相移键控(PSK)调制。 还有一些可用的频率扫描模式,可在频域内产生各种波形,例如锯齿波和三角波。 扫描可以设置为自动进行,也可以设置为通过外部脉冲手动触发每个步骤。 ADF4159具有周跳减少电路,可进一步缩短锁定时间,而无需修改环路滤波器。

所有片内寄存器均通过简单的三线式接口进行控制。 ADF4159采用2.7 V至3.45 V模拟电源和1.62 V至1.98 V数字电源供电,不用时可以关断。

产品详情

The 24 GHz radar sensor platform called Demorad is a novel microwave radar evaluation platform solution with out-of-the-box software examples and easy startup of radar sensor all done within minutes. Demorad platform enables rapid product prototyping aimed at R&D interests in investigating radar and developing radar sensor products that can measure real-time information such as target/object presence, its movement, angular position, velocity, and range from the sensor.


The Demorad platform provides both hardware and software that allows for very fast evaluation and development of 24 GHz radar without the need to have RF microwave and signal chain system expertize, and significantly reduces development time and system expertize during product development phases.


A high performance RF and analog full signal chain including DSP processing, that is, an RF to bits solution is provided that allows for flexible processing on raw acquisition data, allowing radar experiments on a state-of-the art level hardware in a very short time.


Full software support of 24 GHz radar ICs using a software graphical user interface (GUI) and in DSP radar support function libraries with added capability to write raw data for post processing on PC using Matlab tools.

Demorad Details


The Demorad uses ADI’s 24 GHz, multichannel radar solution. The sensor consists of a single PCB with 2 transmitter/4 receiver antennas on the front side connected to the 24 GHz RF chipset and data  acquisition ADC’s and DSP on the reverse side. This forms the basis for a reference design that customers can use to build their final product design.


Figure 2. Demorad full signal chain.


The Demorad uses FMCW radar to detect range and velocity of objects up to 200 m away with a resolution of approximately 75 cm. The field of view (FOV) is approximately 120° in azimuth and 15° in elevation based on the antenna array design. By combining antennas as used in digital beam forming (DBF), the Demorad uses DBF to calculate angular information in the FOV.
