Integrated front-end module features long-range Wi-Fi 6 capacity
Qorvo unveiled a compact integrated front-end module (iFEM) that provides power-efficient and reliable whole-home coverage for Wi-Fi 6 (802.11ax) and eventually Wi-Fi 7 systems. The QPF7250 iFEM extends the Wi-Fi range by 30% over competing devices while increasing capacity to support more access points for smart homes and the Internet of Things (IoT). The Qorvo’s […]
DOCSIS 4.0 ICs deliver 10 Gbps downstream, 6 Gbps upstream
Qorvo announces the availability of the industry’s most complete 1.8 GHz DOCSIS 4.0 product portfolio. DOCSIS 4.0 delivers up to 10 gigabits per second (Gbps) downstream and increases upstream speeds up to 6 Gbps. Greater two-way interaction required for today’s entertainment systems and home and enterprise networks is driving demand for increased downstream bandwidth and […]
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 […]
Dual LNA targets 5G base stations
The QPB9378 from Qorvo covers 5G’s mid band, seen as the sweet spot for range and bandwidth.

High figures of merit characterize 1,200-V Gen 4 SiC FETs
Qorvo announced a next-generation series of 1200V Silicon Carbide (SiC) Field Effect Transistors (FETs) with industry-leading figures of merit in on-resistance. The new UF4C/SC series of 1200V Gen 4 SiC FETs are ideally suited for mainstream 800V bus architectures in onboard chargers for electric vehicles, industrial battery chargers, industrial power supplies, DC/DC solar inverters, as well as […]
Inside a modern power management IC
PMICs today do a lot more than just regulate voltages. Here’s a look at high-end functions these devices provide. Narasimhan Trichy • Qorvo Superior power management and high efficiency have become essential as electronics have become increasingly smaller and more streamlined. The reduction of power dissipation and consequent heat and thermal issues is critical to […]
Wi-Fi 6 RF front ends combine functions
The low-power QFP4526 and high-power QFP4568 bring switches, filters, and amplifiers to Wi-Fi 8 (802.11ax) designs. Wi-Fi 6 (IEEE 802.11ax) access points, routers, gateways, customer-premise devices, and IoT devices need amplifiers to boost signal power to its final levels. The QFP4526 and QFP4568 front-end modules from Qorvo operate at 3.7 V and 5 V power…
Fundamentals of fast chargers for phones and notebook PCs
Overlapping protocols and competing standards have created a confusing landscape for USB chargers. Here are the important differences and similarities of most interest to designers. Masashi Nogawa, Staff Systems Engineer Qorvo The first standard for charging via USB connections allowed power delivery at a 7.5-W maximum. Recently the USB standard jumped up to support 100 […]
