SM3000 OEM module
Buffered modulation and data input(s)
In an organized, periodic manner, the SM3000 processor, a sub-section of the radio chip (U1 – CC2430,
samples digital data inputs introduced to the Module. Data buffering and formatting takes place within the
SM3000 processor, so the actual input data amplitude or rate does not directly modulate the RF carrier and
therefore cannot change the actual RF output level or emission spectrum.
Power supply regulation and local reference oscillator
The radio chip (U1) contains internal voltage regulation to ensure RF output power and modulation remains
consistent. The reference oscillator is crystal-based (X51).
Antenna requirements
The module has an integral antenna (pc-board trace) that cannot be modified or connected to. There is no
mechanism provided for connecting an external antenna.
RF exposure requirements
The module meets the requirements for a portable device that may be used at separation distances of less than
2.5cm from the human body because its output power is below the threshold of 25mW for a 2.4GHz device.
The Module's output power is approximately 10mW EIRP.
Testing in stand-alone configuration
The SM3000 Module was tested as a ‘stand-alone’ device for radiated spurious emissions and found to comply.
Since the device is only battery powered, AC-conducted emissions tests were not applicable.
Label requirements
The label on the module follows the FCC and Industry Canada requirements. The module has two labels as
shown below:
Additionally, the manufacturer’s name is silkscreened on the PC-board:
22/27 Ambient Systems B.V.
