Df is important for prediction of insertion loss in passive devices. If insertion loss is higher than predicted, then power transfer through a device may be too low and a higher power transmitter or more elements would be necessary. Presented here are four methods of extracting Dk and Df from dielectric samples of an unknown material and the pros and cons of each. 

Creating electronic components and circuits with three-dimensional (3D) printers holds great promise for high-frequency-analog and high-speed-digital (HSD) devices. With the right printable electronic materials, 3D printing can form fine feature sizes needed for new levels of dielectric component performance. 

While many have been focused on the 5G C-Band interference issues with commercial airline altimeters, there is also an issue with these same signals interfering with satellite downlinks.

A summary of 5G launches for 2021 from GSA Reports.

It may have gone somewhat unnoticed but for the first time ever, Ansys released software into the open source late last year. The software is PyAnsys, a family of Python packages providing a new, unified programmable interface to the company’s proprietary simulation stack. Learn more about this development.

The 10^th Ericsson Mobility Report was just released and notes that Mobile networks carry almost 300 times more mobile data traffic than in 2011 when the 1^st report was published. Read about the key findings in this report.

We have so much to be grateful for this Thanksgiving, particularly those of us who work in the RF industry. Brent Dietz took some time to reflect on these blessings and was so moved, he wrote new lyrics to a classic hymn.

Dielectric constant is an important starting point for many circuit designers, whether specifying a printed circuit board (PCB) material for a design or with a material in hand and using its Dk in computer circuit simulations. Especially at higher, mmWave frequencies where wavelengths are short and circuit dimensions must be precise, according to a substrate’s Dk, the accuracy of a circuit material’s Dk can impact the success of a prototype. Learn how to determine it accurately.

In contrast, a 5G New Radio (NR) network based on an O-RAN structure is constructed with hardware and software from many different vendors. For the hardware and software to work together, networks require a set of standards for all vendors to meet, including component performance requirements for the network's electrical, mechanical, and environmental operating limits, such as amplifier gain stability with temperature for specified frequency, temperature, and humidity ranges.
