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. Like the QPB9329,
these LNA modules integrate a two-stage LNA and a high-power
switch in a dual-channel configuration. The QPB9337 LNA
modules can control the power down and bypass capabilities
with the control pins on the module. These modules are designed
for wireless infrastructure applications configured for TDD-based
multiple-input and multiple-output (MIMO) architectures.
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. Developed using a high isolation symmetric
topology, the QPC SOI RF Switches offer excellent linearity and
power handling capability. The QPC6054 is a single-pole, single-
throw (SPST) switch. The Qorvo QPC6324 Absorptive High
Isolation Single Pole Double Throw (SPDT) Switch offers high
isolation with excellent linearity and power handling capability.
The QPC6324 switch finds its applications in a wide variety of
4G/5G wireless infrastructure applications.

It's important to keep in mind that 5G won't simply
transform robotics overnight, as many of the applications
and technologies to achieve it are today either embryonic,
in development, or just on the drawing board. Rather,
5G should be viewed as the beginning of a new era
in telecommunications that fully enables robotics and
many other applications for the first time. In addition,
mobile robots are also a long way from being a
mature technology. It will likely take years before they
are massively deployed in applications ranging from
manufacturing and production to agriculture, search
and rescue operations, wide-ranging search and rescue
operations, and many others.
5G will require enormous levels of innovation in every
aspect of the network, from the development of
millimeter-wave communications systems to software-
defined and virtual network architectures, and new
wireless access methods that make it possible for many
robots to operate in a small area without interfering
with each other. Looming above it all is latency, which
researchers must find a way to reduce to virtual
insignificance.
Conclusion
on-a-chip solutions, premium bulk acoustic wave (BAW) and
surface acoustic wave (SAW) filter solutions, and various multi-
chip and hybrid assemblies.
Qorvo is leveraging their product capabilities across low
frequencies up through millimeter wave to respond to the product
demands of the next-generation 5G networks for sub-6GHz
and millimeter wave solutions. A wide variety of products are
embedded in ongoing 5G field trials, and Qorvo has multiple
product development engagements with top OEMs to intersect
network operators' timelines for deployment of 5G networks. Let's
take a look at some of the specific technologies and products that
are bringing 5G and the future of robotics into reality.
Integration Makes It Easy: QPF Front End Modules
Qorvo is a leader in 5G infrastructure front end modules (FEMs).
FEMs are integrated radio frequency (RF) modules that contains
amplifiers, filters, switches, and other components. The Qorvo
QPF4001 GaN Monolithic Microwave Integrated Circuit (MMIC)
FEM is a multi-function device module targeted for 28GHz (26–
30GHz) phased array 5G base stations and terminals. It combines
a low noise high linearity LNA, a low insertion-loss high-isolation
transmit/receive (TR) switch, and a high gain, high efficiency
multistage PA. Operating at a higher frequency Qorvo offers the
QPF4005 Dual Channel FEM, which is a multifunction GaN MMIC
module targeted for 39GHz (37–40.5GHz) phased array 5G base
stations and terminals. It also combines a LNA, a low-insertion-
loss high-isolation TR switch, and a high-gain high-efficiency
multistage PA. Additionally, Qorvo QPF4006 39GHz (37–40.5GHz)
GaN Transmit/Receive Module is targeted for 39GHz phased
array 5G base stations and terminals. Like the others, it combines
a low noise high linearity LNA, low-insertion-loss high-isolation TR
switch, and a high-gain high-efficiency multistage PA.
Signal Boosting: QPL Ultra-Low Noise
Flat Gain Amplifiers
Qorvo QPL9057 Low-Noise Amplifiers provide a flat 2.4dB gain
over a wide bandwidth from 1.5–3.8GHz. These gain amplifiers
provide 22.8dB gain, +32dBm OIP3 at a 50mA bias setting, and
0.54dB noise figure. The QPL9057 gain amplifiers require five
external components to operate from a single positive supply as
they are internally matched using 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 are highly integrated FEMs targeted for Time Division
Duplex (TDD) base stations. These switch modules integrate
a two-stage LNA and a high-power switch in a dual-channel
