Additional Notes
1. The RF ports of the Smart Radio use an MMCX-female connector. The ports are terminated with 50
ohms. Any antenna with desired gain, directivity, and 50 ohm impedance will be compatible. RF
ports include a protection circuit, so even in case of an open connection the Smart Radio will not be
damaged.
2. During ground testing, be aware that the antenna height and Fresnel zone may play a significant role
in achieving long range. Consult the Configuration Guide for more tips.
3. Because the Smart Radio modules generate a fair amount of heat, we recommend mounting them
on the system casing itself for best heat dissipation. The power amplifiers are located on the top-
right corner (near the RF ports, while looking down) of the radio and generate the most heat. The
bottom surface of the radio provides maximum heat conduction out of the module. Please refer to
Appendix C for Heat Power model. Please note that the system thermal design should ensure that
the Smart Radio skin temperature is maintained below the specified limits.
4. During the initial design/evaluation phase, the Samples Characteristics Report may be a useful
reference. It provides the important sample-specific radio characteristics. This report is always
emailed with the shipping documents. Please check with your purchasing coordinator if you don’t
have it.
5. Refer to Appendix A for a mechanical drawing. CAD models are available upon request.
6. For ISM-band Smart Radios, the equipment label should have a note “Contains FCC ID: xxxxxxxx”.
Many Doodle Labs radio models have gone through regulatory certifications. This is an ongoing
activity so please inquire about the specific certification status of the model # used in your project.
7. The Smart Radio Power Supply does not include Galvanic Isolation.
