RF Energy Revolutionizing Cooking

The oven is going under a revolutionary change in the next few years, as RF energy enters the cooking market in the form of new microwave ovens. As the technology is perfected over the next year or two, microwave ovens will be replaced with multiple source solid-state RF ovens which in turn could be introduced into the traditional gas/electric heated ovens most widely used today. It just so happens that this is the 50th anniversary of the first commercial countertop microwave oven sold in 1967--so a good time to celebrate a new innovation, as not much has change with the microwave oven over the last 50 years.

GLOBALFOUNDRIES Positioned to Support High Growth RF Applications

GLOBALFOUNDRIES had a bunch of announcements last week coinciding with their company meeting. From an RF perspective, they announced the availability of the first RF SOI foundry solution manufactured on 300 mm wafers.  According to the release, GF’s new 8SW technology offers a low cost, low power, highly flexible solution with high performance switching, low-noise amplifiers and logic processing capabilities.

Composite Materials Form Radiation-Free DGS Circuits

Filter and antenna designers have long appreciated the benefits of designing distributed high-frequency circuits using defected ground structure (DGS) layouts with different types of circuit materials. DGS shapes are often simple resonant u-shaped slots in the ground plane, intended to enhance the coupling of transmission lines or reduce harmonics. The design approach, which can be used with stripline and grounded coplanar waveguide (GCPW) circuits, is most often used with microstrip circuit designs.

Enabled by Advanced Semiconductor Technologies - 5G mmWave Systems Have Arrived

A year or two ago, it was thought that the first 5G applications would be sub 6 GHz using technologies such as massive MIMO, high orders of carrier aggregation, heterogeneous networks, etc., to achieve better data rates, latency and capacity. But new semiconductor processes and architectures have rapidly progressed making 5G mmWave technology available today at reasonable costs.

mmWave Beams Create New Challenges for 5G

In my last blog, I touched on several aspects of using mmWave spectrum for 5G mobile access that present formidable challenges still under investigation. During the recent RAN1 meeting in Prague, the issue of beams surfaced and progress was made to define the 5G physical layer to address the control and management of these beams.

Microwave Advancements Meet 5G Backhaul Requirements

Skeptics ponder if microwave has the ability to adequately meet 5G backhaul requirements in terms of capacity, complexity, and stringent latency requirements.  Based on what microwave vendors have already demonstrated, Sky Light Research believes that it does and here is why.

Giving Back to Our Communities

Microsemi leads by its actions

We don’t talk very much about local community service and high quality company culture as a technical magazine. I was lucky enough to be invited to a Microsemi reception yesterday afternoon where they showed their commitment to the local Lawrence and Lowell community at their manufacturing facility in Lawrence, MA.
