Better, faster Wi-Fi is here. The two newest versions of 802.11 – that is, Wi-Fi 6 (which runs in 2.4
and 5 GHz spectrum) and Wi-Fi 6E (which uses the 6 GHz spectrum) deliver impressive benefits
to mobile and portable experiences with noticeably higher speed, lower latency and more robust
network connections. Wi-Fi 6/6E is tailor-made for our increasingly connected, on-the-go society, so it’s
no surprise that mobile and portable devices are some of the first to integrate Wi-Fi 6/6E connectivity.
For most engineers, tweaking the RF chain is easier
said than done. RF optimization is considered one of the
most difficult specialties in electrical engineering to master.
That’s why, when working with complex protocols like Wi-Fi,
design teams save time and effort by using pre-integrated
RF solutions, called Wi-Fi front-end integrated circuits (FEICs),
which are purpose-built solutions that complete the RF chain.
FEICs for a Competitive Edge
With the right FEIC on board, new smartphones,
wearables, laptops, tablets and other portable computing
devices can deliver the very best in mobile Wi-Fi
experiences. Whether it’s sharing a smartphone-generated
hotspot with coworkers, streaming a high-definition
movie to a tablet or wearing an Augmented Reality or
Virtual Reality (AR/VR) headset while gaming with friends,
a FEIC can deliver smoother, more reliable Wi-Fi 6/6E
performance while extending battery life and signal range.
Optimized For Wi-Fi 6/6E
A FEIC designed for use with Wi-Fi 6/6E orchestrates
signals so that they don’t interfere with each other and
incorporates individual components that are configured
to perform at their best at each point in the RF chain. The
result is a highly integrated component that simplifies
development while helping to address key challenges
in mobile Wi-Fi 6/6E design, including operation in
noisy environments and the use of multiple antennas for
transmission and reception (Tx/Rx).
- Cleaner Signals
The FEIC’s line-up tuning is done is such a way that
undesired input frequencies are rejected as much as
possible. RF signals are less likely to collide and interfere
with each other, and unwanted signals are less likely
to reach the Wi-Fi SoC. An optimized circuit topology
makes for crisp, clear signals that are easier to manage.
- Stronger Signals
The FEIC’s RF amplifiers boost weak signals without
adding noise. The RF chain becomes more sensitive
and is able to select from multiple input signals,
while also making the signal stronger. There is a tradeoff
here, since amplification consumes energy and
generates heat, so power efficiency is an important
measure of amplifier performance.
- Higher Efficiency
To transmit over a longer distance, it is key to generate
high power levels at the mobile device’s antenna. But
when transmitting at GHz frequencies, it is a challenge
to do so at a good efficiency while still maintaining a
sufficient linearity on the signal. This is where efficient
semiconductor devices and well-optimized RF chains
in a FEIC can make the difference. With the right
combination of semiconductor process and design you
will get a clean and powerful signal while dissipating very
NXP FEICS Give Wi-Fi 6/6E What It Needs
Our WLAN720xx single FEIC product family for WI-Fi 6/6E
builds on our more than 30 years of RF experience and uses
our groundbreaking SiGe:C BiCMOS technology, making
it possible to integrate the power amplifier (PA), switch and low noise amplifier (LNA) into a single chip, with all
the RF blocks in a single device. Other solutions, which use
traditional RF technologies, typically need to split bandwidth,
expand the size of the die or require more complex routing
for a more complicated design. Also, because our single
channel FEICs are housed in very small QFN packages, they
can be placed closer to the antenna, further improving power
consumption and simplifying the layout.
These features deliver tangible, real-world benefits in mobile
and portable applications. Using Dynamic EVM, a measure
of signal quality as an indication, our FEICs work efficiently
to ensure Wi-Fi 6/6E signals experience only minimal
degradation when exposed to noise, distortion and spurious signals.
- Higher Performance
As signals pass through the FEIC and its optimized RF
chain, they remain strong and easy to manage, allowing
the system to dramatically improve data rates and range
for a better experience. For example, AR/VR headsets don’t stutter when
gamers move with the action and video calls,
made on the go don’t get dropped when the caller moves
away from a hotspot.
- Longer Battery Life
The optimized RF chain with its high-efficiency
circuits, saves power at every stage so the system
uses less energy, even during transmission. Enjoy more
time of standout Wi-Fi 6/6E connectivity
before the battery needs a recharge.
Wi-Fi 6/6E is a pivotal technology for mobile and portable
designs and now is the time to start putting it to work.
Our FEICs are designed to enhance performance while
saving time and effort so wireless systems get to market
faster. Our FEICs are fully qualified on leading system-on-chip (SoC) reference designs for mobile and
portable platforms. Because so much of the up-front
engineering work and testing is already done, these
platforms help avoid the challenges and costs associated with
RF design and help development teams deliver exceptional
wireless experiences faster than ever.
