ROHM recommends a 4-layer PCB with a solid ground plane and a separate power plane for the RFC02MM2STFTR. The device should be placed near the antenna, and the PCB layout should minimize signal loops and radiation.
The RFC02MM2STFTR is rated for operation between -40°C and 125°C. Ensure proper thermal design, including heat sinks and thermal vias, to maintain a safe operating temperature. Avoid exposing the device to extreme temperatures during storage or handling.
ROHM recommends a 50Ω impedance-matched antenna with a length of λ/4 (quarter-wavelength) at the operating frequency. The antenna should be placed at least 5mm away from the RFC02MM2STFTR to minimize radiation and ensure optimal performance.
The RFC02MM2STFTR has built-in ESD protection, but additional protection measures are recommended. Use ESD-sensitive handling procedures, and consider adding external ESD protection devices, such as TVS diodes, to the PCB design.
ROHM recommends using a 10nF to 100nF decoupling capacitor between the VCC pin and the GND pin, placed as close as possible to the RFC02MM2STFTR. This helps to reduce noise and ensure stable operation.
