3D-Print Antennas with Printable Dielectric Resin

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.

Dk Testing is Vital to mmWave Circuit Design

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.

Why is the O-RAN Approach Critical for Flexible 5G?

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.
