The difference between active and passive antenna systems

March 3, 2020 By Martin Rowe

5G networks demand new antenna designs to deliver faster speeds for sub-6 GHz and millimeter wave (mmWave) communications. These new antenna technologies, however, often create a tech jargon that can potentially confuse readers. Let’s set the record straight in terms of who is who in the 5G antenna designs. It starts with the difference between…

IoT standards: The End Game

March 29, 2019 By Aimee Kalnoskas Leave a Comment

by Cees Links, Qorvo Quite regularly I get the question: with all these standards around, what should I choose? Zigbee, Thread, Bluetooth Mesh, or Wi-Fi? Or maybe LoRa? Or is it better to wait for 5G and NB-IoT? Of course, these questions create confusion and slow down the adoption of the Internet of Things (IoT). […]

Filters, Part 2: SAW and BAW devices for RF

March 27, 2019 By Bill Schweber Leave a Comment

Part 1 of this FAQ looked at the basic available electronic filters – analog, switched capacitor, and digital – and briefly reviewed the attributes of each. As the frequencies to be filtered reach to 1 GHz and well beyond, while the selectively needed also became narrower, these filter approaches can no longer support many of […]
