National Semiconductor Corp. FCC ID: ED9LMX9838 Request for transmitter modular approval Transmitter Module Characteristics Item Requirements EUT 1 Have its own RF shielding The device is a fully integrated antenna, crystal, RF Transceiver, which has both baseband and RF IC in a encapsulated package. The entire signal chain on receiver (LNA, mixer, filters, level shifters, phase detector, equalizer), transmitter (IQ modulator, DACs, filters, mixer and PA) and synthesizer (PLL, VCO and phase detector) are integrated within the device silicon. The RF silicon design was completed with RF shielding in the silicon design and plastic package. This complies with part 15 FCC requirements for transmission. Additionally, due to the design, it also is immune to external coupling from other circuits in a system. As a result, this device complies with #1 modular transmitter requirements with RF shielding. 2 Have buffered modulation/data inputs (if such inputs are provided), The module has a memory management unit inside of the IC. It buffers the data inputs from the UART terminal. 3 Have it own power supply regulation Internal 2.8V regulator for radio and 1.8V regulator embedded in baseband. 4 Meet the antenna requirements of Section 15.203 Internal antenna 5 Be tested in a stand-alone configuration, i.e., the antenna, AC or DC power and data input/output lines must be connected to the module but, the module must not be inside another case during testing The EUT was tested in a stand-alone configuration. The module was fixed in Development Kit during the test. 6 Be labeled with its own FCC ID number, and if the FCC ID is not visible when the module is installed inside another device , The proposed FCC ID label format will be included in the filing. When the module is installed inside of an end- product, OEM customer will be then the outside of the device into which the module is installed must also display a label referring to the enclosed module. instructed to how to apply the exterior label. Relevant OEM labelling requirements present in the product user manual. 7 The modular transmitter is manufactured so that the user cannot influence the operation of the transmitter that will operate outside of the scope of the regulations. The device is a fully integrated antenna, crystal, RF Transceiver, which has both baseband and RF IC in a encapsulated package. The entire signal chain on receiver (LNA, mixer, filters, level shifters, phase detector, equalizer), transmitter (IQ modulator, DACs, filters, mixer and PA) and synthesizer (PLL, VCO and phase detector) are integrated within the device silicon. 8 Address compliance with the Commission's RF exposure limits in Sections 1.1310 and 2.1093. In addition, spread spectrum transmitters operating under Section 15.247 are required to address RF exposure compliance in accordance with Section 15.247(b)(4). Highest RF conducted output power and EIRP are below the SAR low power threshhold, SAR testing is not applicable

User Manual Revised.pdf Antenna pecification Revised. Hi Helen, Here are the answers to your questions: Question #1: The proposed FCC ID label format shows FCC ID: ED9LMX9838SB, which does not agree with Form 731 or test report. Also FCC DoC logo was used to replace "FCC ID", which is incorrect. Please update the FCC ID label format. Answer: Please see attached revised Label. Question #2: The external photo exhibit contains one photo only, it only shows top view of the product. Please provide the bottom view. Answer: Please see revised external photos, attached. Question #3: Please provide more internal photo(s) to show close view of the component side. The internal photo exhibit includes a PCB board with two connectors, please explain what it is, is it part of the EUT? Answer: Please see attached revised internal photos as well as revised Theory of Operations and Block Diagram. Question #4: The test report indicates the antenna gain is -2dBi, however the antenna spec shows peak antenna gain: 2dBi, please confirm which is correct. You may need to update MPE calculation in the test report. Answer: This was a typo in the PIS that carried to the test report. The antenna specification has been verified as correct, and the report has been updated, including MPE. (Please see attached report.)A new Antenna Specification is also attached. Question #5: The User manual does not contain any regulatory statements. Please add user information as specified in FCC15.19(c) and FCC 15.21, and RF exposure statement specified in FCC15. 247. Since this is a modular approval application, please include instructions the OEM installers as how to label the final product, and how to meet RF exposurement. Answer: Please see attached revised User Manual.
