Historically, limited CW power was available in the millimeterwave frequency range, especially in the higher frequency bands, Ka-band and above. Therefore, power handling was not a major concern for most customers, except in the case of certain dedicated high-power applications or programs in which special attention was required. As semiconductor advancement and applications of such increased in scope, technology such as the Gallium Nitride devices (GaN) enables the expansion of 5G, IoT, small satellite and many other commercial, aerospace and military systems. But due to this, the specification for higher power handling capacity is required for even high frequency devices.
A designer’s project quickly becomes more complicated with the rapid evolution of connected technology. TE Connectivity (TE) is equipped with readily available global engineering expertise. Our teams rapidly work around the globe to understand the ins and outs of each subsystem design, including motors, pumps, heaters, control boards and power systems. TE has the global footprint and knowledge to understand how these subsystems work together across many different industries. This article identifies key areas to consider when designing for efficiency, reliability, and connectivity in today’s connected applications.
This paper shows how TE Connectivity addresses and ensures EMC during component development. The paper uses the example of an interconnection system designed for automotive Ethernet with the focus being primarily on point-to-point connections for sensor data fusion and data transmission via the Ethernet network. It also focuses on managing EMC in data connectivity links based on coaxial technology.
The advantages of multilayer ceramic capacitors over plastic film types include their smaller physical size, lower inductance, and ability to operate at higher temperatures. These advantages make MLC capacitors well suited to high power applications, such as power converter systems in electric and hybrid electric vehicles. When selecting a capacitor to operate at high temperatures, it is useful to understand how its operating conditions can affect its working temperature. This application note explores the factors that affect the working temperature of an MLC capacitor.
Mechanical cracking resistance can be increased by two methods; by reducing the mechanical stress being exerted on the capacitors by PCB design/assembly processes, and by increasing the mechanical strength of the component. This article takes a look at both approaches and will examine Knowles Capacitors’ approach to increasing the mechanical strength through FlexiCap™.
Beamforming is a common technology in the aerospace sector but with 5G NR pushing to integrate beamforming, the market is growing significantly. This drives companies to develop highly integrated ICs, which include a complete analog beamforming network. These ICs will complement digital beam forming elements in order to increase the number of antenna elements forming together a hybrid beamforming setup.
With the next big step in mobile communication, 5G will introduce new RF techniques, new frequencies and signal bandwidths. Ultimately, 5G New Radio (5G NR) will bring higher speed, reduced latency, more capacity and improved reliability. While the system parameters will change, the hardware to enable the new major step in mobile technology towards 5G NR will be different as well. New technologies will be deployed and designs have to follow the new requirements.
Automotive FMCW radars typically operate between 76 GHz and 77 GHz. In some countries, the frequency range between 77 GHz and 81 GHz has become available for automotive radar applications. This paper will review different ways to overcome the challenges of RF measurements in the E band for ultra wide signals. It will look at the demodulation and analysis of a wideband automotive radar signal and discuss the results and main performance parameters.
Many of today’s vehicles tend to include antennas for AM and FM radio, television, GPS navigation, GMS communication, and automated tolling. This white paper discusses how FEKO can provide accurate and efficient solutions in the analysis of integrated windscreen antennas.
This white paper offers a short depiction of FEKO’s waveguide capability with a magic T coupler as an example.
