The CC1150RGVT requires a 50-ohm antenna impedance matching network. A quarter-wavelength monopole antenna or a dipole antenna with a balun transformer is recommended. The antenna should be designed to operate at the desired frequency band (e.g., 868 MHz or 915 MHz).
The transmission power and data rate can be optimized by adjusting the PA_BOOST and PA_DRIVE settings. A higher PA_BOOST setting increases the transmission power, while a higher PA_DRIVE setting increases the data rate. However, increasing the transmission power and data rate also increases the current consumption and reduces the receiver sensitivity.
The recommended crystal oscillator frequency is 26 MHz, and the tolerance should be ±20 ppm to ensure reliable operation and minimize frequency drift.
The CC1150RGVT supports FHSS by using the frequency synthesizer to hop between different channels. The frequency hopping sequence can be programmed using the FHSS_MODE and FHSS_STEP_SIZE registers. The device can hop between 16 different channels, and the hopping sequence can be customized using the FHSS_CHANNEL_MAP register.
The maximum transmission distance achievable with the CC1150RGVT depends on the transmission power, antenna design, and operating frequency. In ideal conditions, the device can achieve a transmission distance of up to 10 km (6.2 miles) at 868 MHz and up to 5 km (3.1 miles) at 915 MHz.
