RF_734_02 04 April 16 Modular Approval Request FCC (KDB 996369 D01 & Part 15.212) FCC ID: X8WLR62XE Items to be covered by Single modular transmitters. Answer from applicant 1. The modular transmitter must have its own RF shielding. Yes. The modular transmitter has its own RF shielding. 2. 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 module has buffered modulation/data inputs to ensure that the device will comply with Part 15 requirements with any type of input signal. 3. The modular transmitter must have its own power supply regulation. Yes. The module contains power supply regulation. There are LDO and DCDC Regulator in chip SX1262. Please refer to chip spec. 4. The modular transmitter must comply with the antenna requirements of Section 15.203 and 15.204(b)(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). Yes. The module contains a unique antenna connector, per Sections 15.203, 5.204(c) 5. The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing. This is intended to demonstrate that the module is capable of complying with Part 15 emission limits regardless of the device into which it is eventually installed. Yes. The demonstrates compliance in a stand-alone configuration 6. The modular transmitter must be equipped with either a permanently affixed label or must be capable of electronically displaying its FCC identification number in accordance with 15.212 (a)(1)(vi)(A) / (B). Yes. The module is labelled with its permanently affixed FCC ID label. 7. The modular transmitter must comply with any specific rule or operating requirements applicable to the transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements. A copy of these instructions must be included in the application for equipment authorization. For example, there are very strict operational and timing requirements that must be met before a transmitter is authorized for operation under Section 15.231. For instance, data transmission is prohibited, except for operation under Section 15.231(e), in which case there are separate field strength level and timing requirements. Compliance with these requirements must be assured. Yes. The module complies with all specific rules applicable to the transmitter including all the conditions provided in the integration instructions by the grantee. 8. The modular transmitter must comply with any applicable RF exposure requirements. For example, FCC Rules in Sections 1.1310, 2.1091, 2.1093, and specific Sections of Part 15, including 15.319(i), 15.407(f), 15.253(f) and 15.255(g), require that Unlicensed PCS, UNII and millimeter wave devices perform routine environmental evaluation for RF Exposure to demonstrate compliance. In addition, spread spectrum transmitters operating under Section 15.247 are required to address RF Exposure compliance. Modular transmitters approved under other Sections of Part 15, when necessary, may also need to address certain RF Exposure concerns, typically by providing specific installation and operating instructions for users, installers and other interested parties to ensure compliance. Yes. The module complies with RF exposure requirements.
