Amplifier targets cellular Band 66
The QPA9901 amplifier from Qorvo provides a typical gain of 36.5 dB covering 2110 MHz to 2200 MHz.
The difference between active and passive antenna systems
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…
Spectrum co-existence challenges in the fully connected car
High-performance RF bandpass filters may hold the key to autonomous vehicle communication without interference. Ali Bawangaonwala | Qorvo, Inc. Continuing advances in technology are making the autonomous vehicle a practical reality, and there is frequent discussion among technologists about Wi-Fi and 5G as enablers of the connected car. Equally important, but less talked about, are […]
IoT standards: The End Game
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
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 […]
Filters, Part 1: Analog, switched, and digital filters
Filters are essential functions in most circuits and systems; as frequencies extend into the multi-GHz range, surface acoustic wave (SAW) and bulk acoustic wave (BAW) filters are needed to meet the design objectives. An engineer I worked with (and whose name I have forgotten) once remarked to about electronic filters (and he was serious): “like […]
GaN Front End Module mitigates 5G expansion costs
Qorvo has expanded its offering for 5G applications with the industry’s first 28 GHz Gallium Nitride (GaN) front-end module (FEM). This new FEM reduces overall system costs for base station equipment manufacturers as they expand into 5G. According to SNS Telecom & IT, the 28 GHz frequency band is widely preferred for early 5G-based fixed […]
Energy efficiency, smart lighting, and the IoT
Sure, smart lights will save energy, but they’ll also be the backbone of systems that can help minimize mini-catastrophes. CEES LINKS, Qorvo THE IoT (internet of things) INCLUDES a rich offering of energy efficiency benefits. Smart lighting is, of course, one of the most common elements of any IoT energy efficiency discussion. Lighting is a […]
A simplified way of devising 5G phased arrays
We recently got a tour of Qorvo‘s new RF front-end module from Qorvo’as Bror Peterson and Keysight’s Osamu Kusanois. The module is said to be the world’s first 39-GHz front-end that integrates a power amp, low-noise amp, and switch in one small package. The module uses gallium nitride technology to get a high power density. […]
