'' Complex modulation
schemes require linear
class-A power amplifiers
that typically exhibit
DC to RF conversion
efficiencies of 15%;
MIMO systems with
multiple power amps are
power hungry. Power
efficiencies will come
through adaptive system
management and spatial
diversity and tracking of
the mobile receiver."
Power Design Complicates RF Wireless Design
Power design is complex, and power assembly design and integrations should be treated as
equally important as front-end design. Reliability and efficiency are key. ADI helps designers
navigate today's power challenges by providing:
• Pre-certified, standards-driven power solutions.
• Reference designs that enable confidence in performance and certification.
• Gerber files for PCBs.
• Integration tools.
• Full MATLAB simulation models to test requirements, standards, and performance.
• Power supply simulation tools, including simulating the supply for special amplifier in
base-station chips, noise, and feedback.
