Production Test Interface Solutions for mmWave and Antenna in Package (AiP)

Incredibly, the number of transistors in integrated circuits (ICs) has tracked Moore’s law, doubling every two years. Equally amazing is the recent jump in IC device operating frequency into the mmWave spectrum. The emergence of 5G, next-generation WiFi protocols, and automotive radar have pushed ICs into these extreme frequency bands to take advantage of the additional available bandwidth. The need for instantaneous data transfer has driven the increasing demand for these new mmWave devices, whether for safety concerns in automotive radar, enormous data networks for 5G cellphone backhaul, or simply the expectation to instantaneously stream 4K video from your tablet to your flat screen. Historically, 6 GHz was the high end of the frequency band for the majority of ICs. Operating frequencies have jumped to 30, 40, 60, and 80 GHz to get the necessary bandwidth for next-generation 5G, WiFi, and automotive devices, respectively. This equates not to a doubling in frequency, but to a gigantic leap that in some cases is greater than an order of magnitude. An additional challenge beyond the rapid growth in operating frequencies is caused by 5G applications driving an emerging need for production over the air (OTA) test of antenna in package (AiP) devices.

Breakthrough Scalability for Automotive Device Test

New Diamondx VI1x Instrument Enables High Multi-site Automotive and Industrial Device Testing

Automotive power electronics IC’s are complex and have stringent test requirements. Typically this limits how many IC’s can be tested in parallel, and thus inhibits the cost-effectiveness of modern highly parallel manufacturing test strategies. The Diamondx platform, with a range of power and automotive instrumentation featuring SmartMux, breaks this barrier and enables maximum efficiency.  VI1x is the latest member of this family of instruments, and it offers the right balance between uncompromising measurement quality and highest parallel test efficiency.  Leveraging a proven fully discrete channel design, the VI1x delivers up to 100mA in the +/-60V range and up to 300mA in the +/-20V range, while offering force and measure current accuracy as low as 1.2nA.  With a 64 channel SmartMux topology, the VI1x dramatically reduces loadboard PCB complexity, speeding time to market and reducing cost and risk associated with leading-edge automotive and industrial power management devices.
