The Importance Of Phase-Coherent RF Signal


As the number of higher-throughput applications grows, so does the need for wider bandwidth and network coverage in wireless systems. Given limited spectrum allocation, wireless communication engineers must look for ways to improve spectral efficiency and the signal-to-noise ratio (SNR) of systems. Multiple-input / multiple-output (MIMO) and beamforming can help RF designers achieve diversity, ... » read more

The Complex Art Of Handling S-Parameters


By Pradeep Thiagarajan and Youssef Abdelkader IC design is transforming at an accelerated pace along with fabrication technology. The need to incorporate more functionality has led to denser dies, multi-die chips, stacked 3D ICs, and advanced packaging. Furthermore, the increasing demand for enhanced connectivity with more and faster access to data continues to drive technology towards highe... » read more

In-Design Thermal Analysis For MMIC And RF PCB Power Applications


Next-generation wireless communication and radar systems often demand increased RF power within a smaller footprint to meet the performance and size requirements of their respective commercial and aerospace applications. As a result, RF front-end electronics are exposed to the risk of higher operating temperatures, which degrade RF performance and threaten device reliability. For many device ma... » read more

MicroLEDs Move Toward Commercialization


The market for MicroLED displays is heating up, fueled by a raft of innovations in design and manufacturing that can increase yield and reduce prices, making them competitive with LCD and OLED devices. MicroLED displays are brighter and higher contrast than their predecessors, and they are more efficient. Functional prototypes have been developed for watches, AR glasses, TVs, signage, and au... » read more

Radar For Automotive: How Far Can A Radar See?


In the previous entries of this blog dedicated to automotive radar, the reason for using radar and the principle of operation of the frequency modulated continuous wave radar were presented. Now, we will focus on the performance of the system, starting with its maximum detection range: how far can we detect an obstacle ahead? We need to have as much foresight as possible, to be able to detect a... » read more

Fan-Out Packaging Gets Competitive


Fan-out wafer-level packaging (FOWLP) is a key enabler in the industry shift from transistor scaling to system scaling and integration. The design fans out the chip interconnects through a redistribution layer instead of a substrate. Compared to flip-chip ball grid array (FCBGA) or wire bonds, it creates lower thermal resistance, a slimmer package, and potentially lower costs. Yet, if the h... » read more

Equipment Suppliers Brace For GaN Market Explosion


A huge GaN market is opening up, driven by consumer devices and the need for greater energy efficiency across many applications. Suppliers are ready, but to fully compete with SiC in high-voltage automotive applications will require further technological developments in power GaN (gallium nitride). Still, the 2020s mark a very high-growth phase for GaN markets. Revenues in the power GaN mark... » read more

The Great Migration To 5G Is Underway


Every decade brings with it a plethora of technology changes, and the cumulative effects of 50+ years of changes in wireless technologies are noteworthy for how they have changed the way we communicate. The 80’s began the era of personal computing along with 1G rollout The 90’s saw the advent of 64-bit microprocessor architecture in consumer devices coinciding with 2G rollout The... » read more
