The CC2544RHBR requires a 50-ohm antenna impedance matching network. A recommended antenna design is a quarter-wavelength monopole antenna with a length of approximately 17.5 mm. TI also provides an antenna design guide and layout recommendations in the CC2544RHBR datasheet.
The CC2544RHBR has a built-in voltage regulator, but it's recommended to use an external power management IC (PMIC) to ensure efficient power management. TI recommends using the TPS62740 or TPS62741 PMICs, which are optimized for low-power wireless applications.
To ensure a robust and secure wireless connection, implement a robust link layer (LL) and a secure encryption mechanism. TI recommends using the TI-RTOS and the SimpleLink CC2544RHBR SDK, which provide a robust LL and encryption mechanisms such as AES-128.
To optimize the CC2544RHBR's performance for low power consumption, use the device's built-in power modes (e.g., sleep mode, idle mode) and adjust the transmission power and data rate according to the application's requirements. Additionally, use the TI-RTOS and the SimpleLink CC2544RHBR SDK, which provide power management APIs and optimized drivers.
To ensure optimal performance, follow the recommended PCB layout and design considerations outlined in the CC2544RHBR datasheet, including keeping the RF signal traces short and away from digital signal traces, using a solid ground plane, and minimizing the use of vias and layer changes.
