The complexities of 5G development in Asia

If robotics and cellular communications seem, strange bedfellows, it’s because the fifth generation of wireless, 5G development in Asia, is that the first to wirelessly address the necessity of such applications instead of just increasing data rates and expanding coverage as previous generations did.

This ambitious standard, called IMT-2020 by the International Telecommunications Union (ITU) that globally regulates them, will accomplish this by completely revolutionizing the way cellular networks are built, the devices they will connect with, the frequencies at which they operate, and therefore the applications they serve.

There’s tons of controversy lately surrounding robotics and the way alongside AI (AI) they’re going to come to rule the planet, including some containing rather draconian prospects for the fate of humanity. The champions of robots believe they’re going to compliment people instead of replacing them, and perform some functions that humans aren’t excellent at anyway.

On the opposite side is a few who believe that robots can take the place of humans in manufacturing and other industries, eliminating many jobs. Whether or not robots will ultimately look down their artificial noses at humans remains to be seen, but 5G is nearly bound to allow them to function more efficiently and serve more applications than ever before.

Besides the very fact that the robots and therefore the entire “ecosystem” required to enable telesurgery and other next-generation robotic applications are still in their infancy, current 4G networks simply don’t have the characteristics required to form them possible.

That is, as they require virtually instantaneous response times, it’ll be essential to scale back a metric called latency to unprecedented levels. Latency is essentially the time span between when input is initiated at one point during a communications link and when it returns with error-free input from another point. Low latency is significant for top reliability machine-centric communication for robotics of tomorrow.

Enabling 5G Infrastructure

Qorvo may be a leading global supplier of RF solutions with a various portfolio of solutions that “connect and protect,” communication applications like radar, Wi-Fi customer premises equipment for home and work, high-speed connectivity in LTE and 5G base stations, cloud connectivity via data center communications and telecom transport, automotive connectivity and other IoT, including smart-home solutions. Qorvo’s vanguard products include gallium arsenide (GaAs) and gallium nitride (GaN) power amplifiers (PAs), low-noise amplifiers (LNAs), switches, complementary metal-oxide-semiconductor (CMOS) system-on-a-chip solutions, premium bulk sound wave (BAW) and surface sound wave (SAW) filter solutions and various multi-chip and hybrid assemblies.

Integration Makes It Easy: QPF front Modules

Qorvo may be a leader in 5G infrastructure front modules (FEMs). FEMs are integrated frequency (RF) modules that contain amplifiers, filters, switches, and other components. The Qorvo QPF4001 GaN Monolithic Microwave microcircuit (MMIC) FEM may be a multi-function device module targeted for 28GHz (26–30GHz) phased array 5G base stations and terminals.

Signal Boosting: QPL Flat Gain Amplifiers

Qorvo QPL9057 Flat Gain Amplifiers are designed to supply a flat 2.4dB gain over a good bandwidth from 1.5GHz-3.8GHz. These gain amplifiers provide 22.8dB gain, +32dBm OIP3 at a 50mA bias setting, and a 0.54dB noise figure. The QPL9057 gain amplifiers require five external components to work from one positive supply as they’re internally matched employing a high-performance E-pHEMT process. Typical applications include mobile infrastructure, repeaters, Time Division Duplex (TDD) or Frequency Division Duplex (FDD) systems, LTE/WCDMA/CDMA/GSM, and general-purpose wireless.

Dual Channels, Different Frequencies: QPB Switch Low Noise Amplifiers

Qorvo’s QPB9329 4.4–5.0GHz Dual-Channel Switch LNA Modules have highly integrated FEMs targeted for Time Division Duplex (TDD) base stations. These switch modules integrate a two-stage LNA and a high power switch during a dual-channel configuration. Similarly, the Qorvo QPB9337 2.3–3.8GHz Dual-Channel Switch LNA Modules are highly integrated front-end modules targeted for TDD base stations. just like the QPB9329, these LNA modules integrate a two-stage LNA and a high-power switch during a dual-channel configuration.

A flick of the Switch: QPC Absorptive High Isolation SOI Switches

Qorvo QPC silicon-on-insulator (SOI) RF Switches like the QPC6054 are specifically designed for cellular, 3G, LTE, and other high-performance communications. The devices have a surface mount design for ease-of-assembly and operate from 5MHz-6GHz.
