Packaging Technology Needs Of Automotive Radar Sensors Chips


Automotive radar systems are typically composed of an antenna, front-end radar sensor and back-end signal processor. Current state-of-the-art automotive radar systems make use of the latest integrated circuit and a wide range of packaging technologies. Let’s look a bit further into the development of automotive radar sensor chips and the packaging technologies being used as solutions for this... » read more

AiP/AiM Design For mmWave Applications — Advanced RF Front-End Design Flows From Concept To Signoff


System requirements for broad bandwidth, millimeter-wave (mmWave) spectrum, phased arrays, and integrated antennas and front-ends are evolving. The challenge for engineers will be achieving the cost, size, and performance requirements that will make these products commercially viable. All these factors align to drive next-generation component integration, which includes embedding the antenna wi... » read more

5G Chips Add Test Challenges


The advent of chips supporting millimeter-wave (mmWave) 5G signals is creating a new set of design and testing challenges. Effects that could be ignored at lower frequencies are now important. Performing high-volume test of RF chips will require much more from automated test equipment (ATE) than is required for chips operating below 6 GHz. “MmWave design is a pretty old thing,” said Y... » read more

Testing AiP Modules In High-Volume Production


Far-field and radiating near-field are two options for high-volume over-the-air (OTA) testing of antenna-in-package (AiP) modules with automated test equipment (ATE) [1]. In this article, we define an AiP device under test (DUT) and examine the measurement results from both methods. Creating an AiP evaluation vehicle Proper evaluation of an ATE OTA measurement setup requires an AiP module. Us... » read more

Challenges Grow For 5G Packages And Modules


The shift to 5G wireless networks is driving a need for new IC packages and modules in smartphones and other systems, but this move is turning out to be harder than it looks. For one thing, the IC packages and RF modules for 5G phones are more complex and expensive than today's devices, and that gap will grow significantly in the second phase of 5G. In addition, 5G devices will require an as... » read more
