WHITE PAPER
5G NR Primer for Amplifier and Filter Design
Future communication systems will comprise many diverse systems that will be implemented
with a wide array of solutions. Providing increased mobile broadband traffic and higher
data rates, as demanded by end users, will require adding more spectrum, making that
spectrum more efficient, and building out ultra-dense network configurations.
Of the RF and microwave hardware components that will support all these different systems,
three main trends will continue to be true.
f
Performance metrics such as bandwidth, linearity, and efficiency are critical and will have a
major impact on devices like power amplifiers (PAs), filters, and antennas.
f
Integration within multi-technology modules and embedded devices will be critical for bringing
high-performance, cost-effective communications products to market quickly.
f
The escalating cost of product development for complex systems will require more coordinated
engineering efforts.
This paper takes a look at the challenges in designing amplifiers and filters for 5G
communication systems and how the Cadence

platform can be
used to simulate amplifier and filter performance under 5G operating conditions.
