Resonant Inc. Strengthens IP Portfolio with the Issuance of the First XBAR®-Related Patents
April 20 2020 - 6:10AM
Resonant Inc. (NASDAQ: RESN), a leader in transforming the way
radio frequency, or RF, front-ends are being designed and delivered
for mobile handset and wireless devices, today announced the first
patents awarded by the U.S. Patent and Trademark Office (USPTO) for
its ground-breaking XBAR® technology designed for 5G and WiFi.
Resonant’s patent portfolio now numbers over 200 patents filed or
issued, more than 50 of which are specifically focused on 5G.
Resonant has filed numerous patent applications
with respect to its XBAR® technology, both domestically and abroad.
Resonant was awarded US Patent No. 10,491,192, titled:
Transversely-excited film bulk acoustic resonator and US Patent No.
10,601,392, titled: Solidly-mounted transversely-excited film bulk
acoustic resonator. Resonant also received an indication from the
US Patent & Trademark Office that a third US Patent, titled
Transversely-excited film bulk acoustic resonators for high power
applications, will issue before the end of April. These are
the first issued patents that protect the company’s novel resonator
structure, which is optimized for the wide bandwidths, high
frequencies, high powers and low loss required for 5G. Realizing
these new requirements is critical for the success of 5G and the
enhanced user experience promised by this next generation wireless
technology.
“In the transition from 3G to 4G, when new spectrum
was allocated, this changed the necessary filter performance, and
hence the required filter structure. What resulted was new 4G
filter structures, Film Bulk Acoustic Resonators (FBAR) and Solidly
Mounted Resonators (SMR). In the same way, 5G has a new spectrum
allocation which is much wider bandwidth (100’s of megahertz rather
than 10’s of megahertz) in order to realize the high data-rates
demanded by today’s users and 5G applications,” stated George B.
Holmes, Chairman and CEO of Resonant. “This requires a new filter
structure, our XBAR, which was designed and optimized specifically
to meet the exacting standards of 5G and WiFi and allow for the
co-existence of these technologies as more users operate in this
high frequency spectrum. The accuracy of Resonant’s Infinite
Synthesized Networks (ISN®) design platform allowed our design team
to explore different structures and focus on the optimum for this
application.”
Building on the initial success and performance
breakthroughs of its XBAR technology, Resonant recently
demonstrated expanded performance for XBAR for RF filters that can
manage the co-existence of 5G and Wi-Fi 6 and 6E networks,
protecting each from co-interference and the resulting degradation
in network performance. Co-existence of 5G and Wi-Fi is an emerging
and significant challenge to real-world deployments. According to
Navian Inc., 5 GHz band for Wi-Fi which is essential for
smartphones sits between the 4.5 GHz and 6-7 GHz bands. If these
frequencies are to be fully utilized, each bandwidth would need a
steep filter. Also with n77 and n79, high-performance filter would
be needed at the same time, since band gap of 200 MHz is too narrow
to be utilized fully.
Resonant documented the performance of the XBAR
resonators in a recently posted whitepaper titled: High Frequency
Resonator is Foundation for High-Throughput 5G Services – And Much
More.

general, please visit the company-hosted 5G Technology Update
Webinar, held on February 27, 2020 on the Events page of Resonant’s
website.

About Resonant’s ISN®
TechnologyResonant can create designs for
difficult bands, modules and other complex RF Front End
requirements that we believe have the potential to be manufactured
for half the cost and developed in half the time of traditional
approaches. ISN is a suite of proprietary mathematical methods,
software design tools and network synthesis techniques that enable
us to explore a much larger set of possible design solutions that
regularly incorporate our proprietary technology. We then quickly
deliver design simulations to our customers, which they manufacture
or have manufactured by one of our foundry partners. These improved
solutions still use Surface Acoustic Wave (SAW) or Temperature
Compensated Surface Acoustic Wave (TC-SAW) manufacturing methods
and perform as well as those using higher cost manufacturing
methods such as Bulk Acoustic Wave (BAW). Resonant's method
delivers excellent predictability, enabling achievement of the
desired product performance in roughly half as many turns through
the fab. In addition, because Resonant's models are fundamental,
integration with its foundry and fab customers is seamless because
its models speak the "fab language" of basic material properties
and dimensions.
