Filters, Part 1: Analog, switched, and digital filters

November 4, 2020 By Bill Schweber

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 […]

Filters, Part 2: SAW and BAW devices for RF

March 26, 2019 By Bill Schweber

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 […]

Bulk acoustic wave filters make life easier for Wi-Fi front-end designers

April 25, 2018 By Lee Teschler

Wi-Fi/LTE system models

BAW filters help overcome the biggest challenges facing Wi-Fi front-end designs, including thermal management, interference, and RF linearity. Cees Links |Qorvo Wireless Connectivity Smart homes are getting smarter. So they increasingly make heavy demands on their internet routers, so much so that traffic demands are exceeding the capacity of the single-router model. Retailers and businesses […]

Ultra-broadband amplifiers have output power of tube amplifiers in compact, solid-state modules

March 3, 2017 By Aimee Kalnoskas

801.11ax

Qorvo has introduced three new solid-state power amplifier (SSPA) modules that further expand the power and frequency range of the company’s Spatium® amplifier family. The modules are optimized for electronic warfare applications, enabling defense customers to use ultra-wideband SSPA technology as an alternative to traveling wave tube amplifiers (TWTAs). “The need for wider bandwidth, higher frequency […]
