Infineon acquires another chip company

 


【Lansheng Technology News】On October 4, Infineon announced that it has acquired Zurich-based startup 3db Access AG (3db). This company is a pioneer in secure low-power ultra-wideband (UWB) technology and has become Preferred intellectual property provider for major automotive brands. Infineon will acquire 100% of the company's shares. The parties have agreed not to disclose the transaction amount.


It is reported that 3db Access AG is a fabless semiconductor company focusing on secure ultra-wideband (UWB) low-power chips and is headquartered in Switzerland. 3db Access pursues centimeter-level, low-power and secure UWB positioning technology, and provides accurate and secure UWB positioning solutions through flexible cooperation models to enable access to applications such as vehicles, buildings, tracking tags, IoT devices and mobile payments. 3db Access's products are divided into three categories: LRP UWB (low-rate pulse), HRP UWB (high-rate pulse), and HRP/LRP (IEEE 802.15.4z). Among them, low-rate pulse chips can be used in low-power IoT devices , such as smart watches, wearable devices, sensors, etc.


The acquisition further strengthens Infineon’s product portfolio in the areas of secure intelligent access, precise positioning and enhanced perception. Infineon is now adding UWB to its connectivity solutions, including Wi-Fi, Bluetooth®/Bluetooth® Low Energy and NFC solutions. The first IoT use cases include secure access and authentication, precise location tracking and indoor navigation, and presence detection using UWB radar.


UWB is a wireless communication technology that uses frequency bandwidths above 500MHz and uses nanosecond-level non-sinusoidal narrow pulses for data transmission. UWB has the characteristics of low system complexity, insensitivity to channel fading, and strong penetration ability. In recent years, it has attracted much attention in applications such as high-precision positioning and radar.


The UWB transceiver system consists of two parts: radio frequency and baseband. The industry usually uses two chips to implement the radio frequency and baseband functions respectively. With the application of UWB technology in smartphones, car digital keys and other fields, SoC solutions that integrate radio frequency, baseband, MCU and other functions as well as BLE (Bluetooth) and other subsystems are more competitive in terms of cost, performance and system application convenience. , becoming the main research and development direction of UWB chip design companies. According to ABI Research, the UWB chip market will grow at an average annual rate of 13% by 2028, reaching approximately US$31 billion.

What are the Benefits of Power Optimizers?

Image
  Power optimizer for solar panels is a DC/DC converter that is connected to each solar panel in the PV system, turning them into smart modules. By constantly monitoring the maximum production capacity of each individual solar module, optimizers can increase your PV plant energy production – potentially increasing revenue and shortening system payback time. Simply put, the main benefit of power optimizer is that it maximizes the performance of each panel individually. What are the benefits of power optimizers and why are they needed? When installing solar panels, the panels are connected into groups or arrays. In the case of roof-mounted and in-roof panels, there are usually 12-20 solar panels in one group. If the productivity of one of these panels decreases (shadows from trees and clouds, dust, bird droppings, failures of PV components and other factors), then the productivity of the whole group decreases. Defective or shaded panels may produce 15 to 25 percent less solar energy ...

What is a Power Conditioner?

Image
  Looking to protect your sensitive and expensive electronics? Surge protection is a great start, but power conditioners also offer valuable protection for components in entertainment and sound systems, as well as home office devices. What does a power conditioner do that a surge protector can’t? Surge protectors are a great defense against damaging voltage spikes. However more than surges and spikes can effect certain sensitive electronic devices. Radio frequency interference (RFI), electro-magnetic interference (EMI) and voltage fluctuations can also effect sound, entertainment, and office devices, causing a reduction in sound and picture quality. How does it work? Power conditioners act as a buffer between the outlet and your system, smoothing out voltage fluctuations as well as radio and electromagnetic interference that can effect system performance. Initially used in industrial, research and laboratory applications, not long after the introduction of home computer systems, th...
