Automotive radar technology is on the rise. Whether it is for current blind spot detection systems or for developing autonomous driving control, high performance, high reliability, compact size, and low cost are indispensable factors and motivations for the continuous development and improvement of core automotive radar technologies. Automotive radar is an essential component of driver...
As complexity and density increase, the long-term reliability of RF/microwave circuit components becomes more challenging to characterize. Printed Circuit Boards (PCBs) comprise numerous active and passive components, whose performance can vary over time and with operating environment temperatures. Additionally, PCB substrate materials, such as dielectrics, copper foil conductors, solder mask inks, and final finishes, may change over time, influenced...
Introduction This article introduces the various backhaul technologies available for 5G networks, focusing on E-band wireless RF links and how they support the continued deployment of 5G networks around the world. We will perform a technical analysis of the system requirements necessary for E-band technology. We will then map the results to the physical radio...
In the Texas Instruments technical article, “How low-power 60GHz mmWave radar sensors enable high-precision sensing in more applications,” we discussed how 60GHz millimeter-wave (mmWave) radar sensors enable high-precision sensing in industrial and consumer electronics applications. In this article, we will explore how low-power 77GHz radar sensors can help achieve reliable and accurate sensing in other challenging applications....
Electrical performance consistency is critical for producing high-volume printed circuit boards (PCBs). As PCB applications move to higher frequencies, such as fifth-generation (5G) cellular wireless networks at millimeter-wave frequencies and 77 GHz automotive radar, any inconsistencies on the PCB become very noticeable, especially when the circuits operate at shorter wavelengths of millimeter-wave frequencies. There will always be...
1. Definition of PCB high frequency board High-frequency boards refer to special circuit boards with higher electromagnetic frequencies. They are used in high-frequency (frequency greater than 300MHz or wavelength less than 1 meter) and microwave (frequency greater than 3GHZ or wavelength less than 0.1 meter) PCBs. They are produced on microwave-based copper-clad boards using some of the...
The electronics industry has undergone many changes over the past few years. Nowadays, millimeter wave radar and millimeter wave communication frequently appear in our sight. In particular, Huawei has made remarkable achievements in 5G, and millimeter wave technology has been put on the table. Why does millimeter wave technology play such a key role in 5G and smart cars?...
As complexity and density increase, the long-term reliability of RF/microwave circuit components becomes more difficult to characterize. Printed circuit boards (PCBs) contain many active and passive components whose performance changes over time and over operating ambient temperature. In addition, the substrate materials of the PCB, such as the dielectric, copper foil conductors, solder mask, and final plating,...
There are some things in life that seem to set the standard for whatever area that you are currently involved in. Some will always compare baseball players to Jackie Robinson, while others will say that nobody could carry a tune the way that Elvis did. For me, I tend to equate the standard printed circuit...
Copper foils, for the wide range of Rogers’ high frequency circuit substrates, are designed to provide optimum performance in high reliability applications. There are various types of copper foil are offered; in a range of weights (thicknesses). Their characteristics differ, and an understanding of these differences is important to ensure the correct selection of copper...
