Skyworks and Xilinx Enable 5G Across Newly Available C-band Spectrum

Companies Demonstrate 280 MHz C-band
Solution For 5G Infrastructure
Skyworks Solutions, Inc. (Nasdaq: SWKS), an innovator of
high-performance analog semiconductors connecting people, places
and things, together with Xilinx, Inc. (Nasdaq: XLNX), recently
demonstrated compliance with 3GPP linearity and bandwidth
requirements for C-band signals that are critical for enabling
next-generation 5G infrastructure. The 280 MHz instantaneous
bandwidth (IBW) solution that was demonstrated by the companies
uses a Xilinx Zynq RFSoC Gen 3 and a Skyworks SKY66523-11
high-efficiency power amplifier (PA). The demo is available via
video by visiting the Xilinx Xclusive Blog.
The SKY66523-11 wide instantaneous bandwidth high-efficiency PA
has an operational frequency range of 3550 to 4200 MHz and is ideal
for use as both a C-band 5G NR small cell PA and as a driver
amplifier for Massive MIMO and macro base stations. U.S. C-band
spectrum refers to mid-band frequencies in the range of 3.7 GHz to
3.98 GHz, which are optimal for 5G because they provide the right
balance of geographic coverage, capacity and speed. At nearly $81
billion, the recent U.S. Federal Communication Commission (FCC)
auction of 280 MHz C-band spectrum was the highest-value spectrum
sale in history.
The first portion of the C-band spectrum, referred to as
“A-block,” is expected to be available by the end of this year. In
anticipation of deploying as soon as the A-block spectrum becomes
available, OEMs are already in the process of designing C-band
systems. B-block and C-block spectrums are expected to be available
by the end of 2023.
The demo incorporating the SKY66523-11 PA and the Xilinx
Adaptable SoC shows multiple scenarios covering the full 280 MHz
C-band spectrum with an occupied bandwidth (OBW) of up to 200 MHz,
which is the maximum bandwidth won by any operator during the
recent auction. In all scenarios, the combined Skyworks/Xilinx
solution achieved Adjacent Channel Leakage Ratio (ACLR) compliance,
a critical requirement of the 5G specification, making this
combination ready for immediate A-block deployment and future
B-block and C-block deployments.
“The majority of early 5G deployments are leveraging Xilinx
technology for the radio. Along with our silicon platforms, Xilinx
is providing industry leading signal processing IP that is enabling
both wider bandwidths required by C-band while also maintaining
energy efficiency in the radio,” said Brendan Farley, vice
president of wireless engineering at Xilinx. “This demonstration,
together with Skyworks PA technology, shows how our Adaptable
Digital RF IP can quickly scale to address new and emerging radio
requirements.”
“Our demo with Xilinx highlights the readiness and maturity of
this 5G solution and with the C-band auction concluded and winners
announced, the next phase is for deployments as rapidly as
possible,” said Yusuf Jamal, senior vice president and general
manager of diversified analog and AI solutions at Skyworks. “The
C-band is a unique and important piece of the 5G landscape, and
Skyworks has long been investing in and preparing to deliver
innovative technologies that address this new spectrum.”
The Xilinx Zynq RFSoC Gen 3 is in full production and contains
the direct RF transceivers along with the adaptable CFR (Crest
Factor Reduction) and DPD (Digital Pre-Distortion) IP. The
SKY66523-11 is part of a 5 × 5 mm pin-to-pin compatible family of
PAs supporting major 3GPP bands and is sampling now. To learn more
