This paper addresses Qorvo’s integrated approach to thermal design that leverages modeling, empirical measurements (including micro-Raman thermography), and finite element analysis (FEA) for high performance microwave GaN HEMT devices and MMICs. This methodology is highly effective and has been empirically validated. By properly addressing FEA boundary condition assumptions and the limitations of infrared microscopy, resulting model calculations are more accurate at both the product and end application level than traditional methods based on lower power density technology.

This limiter doesn’t require bias, and contributes less than 0.6 dB in insertion loss.
Qorvo offers a new high-power receive protection circuit, or limiter, that is capable of withstanding up to 100 W incident power levels. This limiter operates in the 0.05 to 6 GHz frequency range, and permits less than 17 dBm flat leakage to pass through while contributing less than 0.7 dB in insertion loss.

Advancements in Gallium Nitride technologies are leading to amplifier operation at higher powers, supply voltages, and frequencies. The whitepaper includes load-pull measurements, thermal considerations, and EM simulations of the input/output matching networks.
What is the point of a bunch of connected things in the home if there if there is not something, or someone, to tie them all together in one serviceable platform? The smart home revolution has taken a lot longer to get up and running due to the disagreements over what protocols and platforms should be used in the base technologies, as well as the poor choices in consumer words like “smart home” and “IoT.” Instead of trying to sell connected things and devices, a shift should be made to sell services that bring the connected devices together in a “big picture” kind of way.
Solid state amplifiers can be constructed through the use of MMIC amplifiers to reach output powers and performance levels that have only been achievable by traveling wave tube amplifiers (TWTAs). This white paper demonstrates building a 120 Watt power amplifier operating from 27 to 31 GHz.
Carrier aggregation (CA) enables mobile network operators worldwide to provide faster data, and allows mobile devices to communicate on multiple LTE bands simultaneously. This, however, creates the challenge of avoiding interference between the bands while keeping up good reception and battery life. Multiplexers are an excellent solution for CA combinations that use closely spaced bands since they provide isolation between and within bands, while allowing them to connect to the antenna at the same time. This white paper discusses the challenges of carrier aggregation, and the important benefits of using multiplexer solutions to solve them.
The design complexity and number of bands in small cell base stations are increasing at a rapid rate. This article is the second part in a two-part series on the topic of small cell base stations. It discusses Qorvo’s insights on the top trends and how to overcome the challenges of designing small cells.
This article is the first part in a two-part series on the topic of small cell base stations. Part 1 covers the basics of small cells and how they fit into the evolution of 4G and 5G.
RF engineers are continually challenged when designing RF front-ends for mobile devices. Not only do they have to deal with balancing multiple frequency bands, fewer SKUs, and difficult coexistence requirements, another LTE power standard has emerged to further complicate the RF front-end design for mobile handsets.Qorvo’s blog article offers advice on meeting the new Power Class 2 standard.
Qorvo’s offers patented Spatium RF power combining technology to provide a highly reliable, efficient alternative to traveling wave tube amplifiers (TWTAs) for commercial and defense communications, radar, electronic warfare (EW), and other defense systems.
The average number of frequency bands in mobile devices has more than doubled in the last few years. Qorvo is leveraging its filter technologies, such as NoDrift and LowDrift BAW and SAW, to create filters, duplexers, and multiplexers to tackle the challenges of 4G and 5G mobile devices.
Today’s smartphone market has expanded into several categories with differing design goals and priorities, which require different approaches to RF front end (RFFE) integration. Modern packaging techniques make it possible to combine multiple RFFE components into integrated modules which help smartphone manufacturers accelerate the design and manufacture of new handsets. However, since there are two key smartphone categories – flagship phones and mid-tier and entry-level handsets – it raises the question of what would be the right level of RFFE integration and the best integration approach for each one?
How do operators avoid interference between bands while minimizing insertion loss? Multiplexers. They are designed to integrate the required filters for multiple aggregate bands, provide isolation within and between the bands, and allow them to simultaneously connect to the antenna.
This white paper discusses three key filtering challenges addressed by BAW filter technology: 802.11p in the DSRC band, LTE-Wi-Fi coexistence, and satellite radio. It also examines reliability and temperature stability considerations specific to automotive use.

In addition to being “greener,", 5G has goals of 1 ms latency, 100 x network energy efficiency, 20 Gbps peak data rates, and 10 Mps/m2 area traffic capabilities. This article discusses how RF Gallium Nitride (GaN) technology can be used for emerging 5G technologies.
The name “Internet of Things” (IoT) can be misleading in that it does not actually refer to a specific group of things. It really isn’t a new concept either, rather a maturing technology that is making its way into the mainstream eye. Just like every other universally connected device, it operates over our regular internet with familiar applications in wearables and the smart home. So what is the real value of IoT? This white paper provides information on what the IoT has to offer now and in the future, and what defines its true value.
Comcast released the results of a survey from earlier this year providing valuable insights into why consumers are interested in smart home services, what features are most desired, and how they plan to use smart home technologies. The biggest find of the survey is that consumers are more interested in a smart home as a service (SHaaS) over connected devices that remotely control devices in the home. This application note discusses SHaaS, its components, and how it works.
The telecommunications sector accounts for roughly 4 percent of the global electricity consumption. However, the sector is actively participating in efforts to reduce energy use – both for economic reasons, such as reducing operating expenses, and for environmental reasons.
Improvements have been made to GaN amplifiers at microwave frequencies that have increased their generated output power levels while also shrinking the size of the system. These developments, however, present the challenge of providing sufficient thermal management. This Qorvo® application note discusses the thermal issues involved with using high-powered, small packaged (e.g. QFN) GaN amplifiers within high power CW systems. Download the full paper for considerations on component mounting in order to provide a low thermal impedance path to the system heat sink for optimum operation and reliability, using the TGA2307-SM as an example.
Carriers are able to deploy more spectrum range, add capacity, and improve cell edge performance through the densification of small cell outdoor technologies. Since small cells differ in power level, geographical coverage, regional band allocation, and the number of users serviced, OEMs must produce their own small cells to accommodate several stock keeping units. Qorvo offers innovative RF solutions such as filters, amplifiers, switches, and antenna tuning devices that enable customers to meet their design requirements for small cell applications.
The cellular machine-to-machine value-added services market is poised to dominate the transportation, utility, eHealth, and emerging IoT markets.
