The requirement of FCC 15.212 as below: Item § 15.212 RequirementY/N Comments (i) The radio elements of the modular transmitter must have their own shielding. The physical crystal and tuning capacitors may be located external to the shielded radio elements. Yes The modular has RF shielding, please refer to the EUT photo. (ii) The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with part 15 requirements under conditions of excessive data rates or over-modulation. Yes The modular transmitter has buffered modulation/data inputs, Buffered data inputs stage has been integrated in chip (Model: FCS960K). (iii) The modular transmitter must have its own power supply regulation. Yes The modular transmitter has its own power supply regulation. Please refer to the Block Diagram. (iv) The modular transmitter must comply with the antenna and transmission system requirements of §§ 15.203, 15.204(b) and 15.204(c). The antenna must either be permanently attached or employ a “unique” antenna coupler (at all connections between the module and the antenna, including the cable).
