Compare Materials in a Meaningful Way

Selecting a circuit board material for an application often comes down to a choice based on which has better specifications on the data sheet. Two different PCB materials from different suppliers might look identical in terms of key specifications, such as dielectric constant (Dk) and dissipation factor (Df), making a choice difficult. But how close are those two materials really? When can the data sheets look the same but the two materials be quite different?

Hybrid Multilayer PCBs Help Keep Vehicles Safe

Advanced automotive electronics systems have relied on the reflections from on-board vehicular radar systems for some time. The vehicular radars are often fabricated on what are known as hybrid multilayer PCBs. These are PCBs formed of different kinds of circuit-board materials, matching the characteristics of the different materials to the needs of the different circuit functions, from DC through 77 GHz. Learn about designing with these new layers to realize better performing circuits at a lower cost.

Satellite 2018 Review - Snowed In!

I was suppose to fly down to DC on Tues  to spend a couple of days catching up on the newest trends and products at Satellite 2018. But the Nor'easter dumped 2 feet of snow on Boston and every flight I could find was cancelled. So I remotely monitored the happenings at the event and collected the following materials from press releases and emails about what was on display for RF/microwave products.

Don’t underestimate 5G and IoT rollout

Lessons learned from MWC 2018

Mobile World Congress solidified that 5G is fast approaching with deployments this year. In the US, Verizon is rolling out 5G millimeter wave Fixed Wireless Access in many cities and AT&T is rolling out 5G mobile service. T-Mobile will not be far behind with their dual band 600 MHz and 28 GHz 5G rollout starting Q2 of next year.

802.11ax Going Live

With all of the focus on 5G these days, we tend to forget about Wi-Fi which actually carries the bulk of mobile traffic relatively effortlessly. That is not typically the case at events where there are hundreds or thousands of people using their mobile devices in a confined area. But the upcoming generation of Wi-Fi, 802.11ax, will change those poor service experiences into noticeable better ones.
