7 Application, Implementation, and Layout
NOTE
Information in the following Applications section is not part of the TI component specification,
and TI does not warrant its accuracy or completeness. TI’s customers are responsible for
determining suitability of components for their purposes. Customers should validate and test
their design implementation to confirm system functionality.
Few external components are required for the operation of the CC1350 device. Figure 7-1 shows a typical
application circuit.
The board layout greatly influences the RF performance of the CC1350 device.
On the Texas Instruments CC1350_7XD-Dual Band reference design, the optimal differential impedance
seen from the RF pins into the balun and filter and antenna is 44 + j15.
Figure 7-1 does not show decoupling capacitors for power pins. For a complete reference design, see the product
folder on www.ti.com.

7.1 Simplelink CC1350 LaunchPad Bluetooth and Sub-1 GHz Long Range Wireless
Development Kit
The CC1350 LaunchPad combines a Bluetooth™ Smart
®
with a Sub-1 GHz radio for the ultimate
combination of easy mobile phone integration with long range connectivity including a 32-bit ARM
®
Cortex
®
-M3 processor on a single chip.
The CC1350 device is a wireless MCU targeting low power, long range wireless applications. The CC1350
device contains a 32-bit ARM
®
Cortex
®
-M3 processor that runs at 48 MHz as the main processor and a
rich peripheral feature set that includes a unique ultra-low power sensor controller. This sensor controller
is ideal for interfacing external sensors and for collecting analog and digital data autonomously while the
rest of the system is in sleep mode.
