TI recommends a 4-layer PCB with a solid ground plane, and placing the CC8531RHAT near the antenna to minimize noise and ensure optimal performance.
Use a 50-ohm antenna with a quarter-wavelength monopole or a dipole antenna, and ensure the antenna is matched to the CC8531RHAT's output impedance. TI provides antenna design guidelines in the application notes.
The maximum transmit power of the CC8531RHAT is +20 dBm (100 mW), but this can be limited by regulatory requirements and the specific application.
Use the CC8531RHAT's built-in frequency synthesizer and the SPI interface to control the frequency hopping sequence. TI provides example code and application notes for frequency hopping implementation.
The CC8531RHAT is specified to operate over a temperature range of -40°C to +85°C and a supply voltage range of 2.2 V to 3.6 V. However, performance may vary outside of these ranges, and engineers should consider temperature and voltage compensation in their design.
