High-gain GaN amps handle L-band applications
Qorvo introduced the highest gain 100-watt L-band (1.2-1.4 GHz) compact solution: a GaN-on-SiC power amplifier module (PAM) targeting commercial and defense radar applications. The QPA2511 GaN-on-SiC PAM includes an integrated two-stage amplifier solution offering 60% power added efficiency in a circuit size 70% smaller than equivalent two-stage solutions. This unparalleled performance significantly reduces overall system power […]
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 […]
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 […]
Bulk acoustic wave filters make life easier for Wi-Fi front-end designers
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 […]
802.11ax modules and BAW filters improve coverage, lower costs
The expanded, high-efficiency portfolio of 802.11ax integrated modules and advanced filters from Qorvo are designed to improve Wi-Fi coverage, enables smaller end products, and reduces costs for consumers, service providers and manufacturers. 802.11ax will greatly increase network capacity by supporting up to eight simultaneous data streams, each delivering up to 1.2 Gbps, to connect many more […]
Quarter-watt balanced amplifier covers 2.3 – 2.7 GHz
The QPA9807 from Qorvo is a balanced amplifier module with embedded hybrid couplers to convert to single ended input and output ports. The module has an enable pin to allow for shutting down of the amplifier. The module requires minimal external components which are VCC choke inductors, decoupling caps and resistors for bias control. The […]
Half-watt balanced amplifier covers 600 to 1,000 MHz
The QPA9805 from Qorvo is a balanced amplifier module with embedded hybrid couplers to convert to single ended input and output ports. The module has an enable pin to allow for shutting down of the amplifier. The module requires minimal external components which are VCC choke inductors, decoupling caps. The QPA9805 provides +27.4 dBm P1dB […]
Ultra-broadband amplifiers have output power of tube amplifiers in compact, solid-state modules
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 […]
