RF-IF building block
A history of RF innovation
NXP’s portfolio of highly integrated solutions for low-voltage,
battery-operated applications, which includes RF/IF building
blocks, user-interface products, and RF discretes, incorporates
the best of our industry-leading expertise in wireless
technology.
Every product in this category reflects the know-how gained
from a history of RF innovation in cellular communications,
peer-to-peer wireless networking, RFID tags, and high-end
manufacturing.
The result is a series of RF solutions that bring high integration
and superior performance to a wide range of low-voltage,
battery-operated wireless applications in Unlicensed Part 15
frequencies.
Wide selection of package options
All our RF/IF solutions are available in a wide range of package
options that support miniaturization and increase design
flexibility. Included in that list are innovative QFN packages
that deliver a footprint significantly smaller than a standard
SSOP20 or SO16 package.
Demo board kits
Many of our demo board kits are free in single quantities, so
you can turn designs quickly. Others are available for order
through various NXP distributors.
Free application support
We know how vital it is to provide developers with more than
just technology. To make design-in as fast
and easy as possible, we support all our RF products with
ready-made design kits and provide in-depth application
support – all absolutely free of charge.
