SC189CULTRT Frequently Asked Questions (FAQ)
-
A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the RF traces as short as possible and use 50-ohm impedance matching to minimize signal reflections.
-
Implement frequency hopping, use a high-quality antenna, and consider using a shielded enclosure to reduce electromagnetic interference (EMI). Additionally, use error correction mechanisms like CRC and retransmission to ensure data integrity.
-
The maximum transmission distance depends on the environment, antenna gain, and transmission power. In ideal conditions, the SC189CULTRT can achieve a range of up to 10 km (6.2 miles) with a high-gain antenna and optimal transmission power.
-
Optimize transmission power consumption by adjusting the transmission power level based on the distance between devices, using a low-power mode when possible, and implementing a sleep mode or duty cycling to reduce power consumption during idle periods.
-
Choose an antenna with a high gain (e.g., 5 dBi) and a suitable radiation pattern for your application. Ensure the antenna is impedance-matched to the SC189CULTRT's 50-ohm output, and consider using a antenna with a built-in balun to simplify the design.
