The RF Performance Line is a family
of industry’s highest performance RF
parts, including RF transceivers and
a transmitter. The parts operate in the
169/315/433/868/950MHz frequency
bands. RF Performance Line offers
a new level of RF selectivity and
blocking. With 65dB adjacent channel
rejection and 90dB blocking, robust
applications can be built even without
an external SAW filter.
The RF Performance Line devices are
distinguished by supporting different
RF channel bandwidths, data rates
and RF regulations. See tables for RF
regulations supported and feature set.
Complete RF and MCU development
is done with the RF Performance Line
development kit. Out-of-the box, RF
range and performance can be tested
using the free SmartRF™ Studio and
RF Packet Sniffer PC software. Code
development can be done on the
MSP430F5438A used in the develop-
ment kit, which also includes peripher-
als like a dot matrix LCD display and
various sensors.

Category 1 radio on the market.
Significant cost reduction compared
to today’s discrete solutions.
• Longrange,10sofkilometers
out-of-the-box with the development
kit.
• Morereliablelinks,nofalsesync
detects in noise.
• <3mARXsniffmodecurrent
consumption. Extended battery life.
