ATSAMR30M18A User manual RF Trace Layout Design Instructions The ATSAMR30M18A module transmitter is certified with 1. A SMA(1) connector and micro strip layout 2. On-board chip antenna and micro strip layout This section describes the PCB stack up, mechanical details of the PCB trace leading up to SMA connector for case 1 and up to chip antenna for case 2. The host PCB can follow these trace design to maintain compliance under the modular grant(FCC) and certificate(IC). Schematics, BoM, Layout source files and Gerber files are available for download on the SAMR30M18A product web page. Below is a snapshot of the schematic diagram for the host board showing the RF frontend. For case 1, R115 will be populated and L106 will be not populated. For case 2, L106 will be populated and R115 will be not populated. Note:

(1) If the host board of ATSAMR30M18A is designed to have an antenna port that is accessible to the end-user, RP (Reverse Polarity)-SMA socket must be used. If an RF coaxial cable is used between the module RF output and the enclosure, then an RP-SMA connector must be used in the enclosure wall for interface with antenna. Trace layout dimensions:

The measured Tx power should be within the datasheet specification for Transmit output power. Regulatory Approval United States(FCC) The ATSAMR30M18A module has received Federal Communications Commission (FCC) CFR47 Telecommunications, Part 15 Subpart C Intentional Radiators modular approval in accordance with Part 15.212 Modular Transmitter approval. Modular approval allows the end user to integrate the ATSAMR30M18A module into a finished product without obtaining subsequent and separate FCC approvals for intentional radiation, provided no changes or modifications are made to the module circuitry. Changes or modifications could void the users authority to operate the equipment. The user must comply with all of the instructions provided by the Grantee, which indicate the installation and/or operating conditions necessary for compliance. The finished product is required to comply with all applicable FCC equipment authorization regulations, requirements and equipment functions that are not associated with the transmitter module portion. For example, compliance must be demonstrated: to regulations for other transmitter components within a host product; to requirements for unintentional radiators (Part 15 Subpart B), such as digital devices, computer peripherals, radio receivers, etc.; and to additional authorization requirements for the non transmitter functions on the transmitter module (i.e., SDoC or certification) as appropriate (e.g., Bluetooth and Wi-Fi transmitter modules may also contain digital logic functions) ATSAMR30M18A has been tested with BPSK-ALT-40, OQPSK-SIN-250 and OQPSK-SIN-1000-SCR-ON PHY modulation modes for FCC modular approval. The user must restrict the PHY modulation mode to the above specified modes for usage in United states. Labelling and User Information Requirements Due to the limited module size of ATSAMR30M18A (12.7 mm x 11 mm), the FCC identifier is displayed only in the datasheet and packaging box label. FCC identifier cannot be displayed on the module label. When the module is installed inside another device, then the outside of the finished product into which the module is installed must display a label referring to the enclosed module. This exterior label should use the following wording:

For the ATSAMR30M18A:

Contains Transmitter Module FCC ID: 2ADHKR30M or Contains FCC ID: 2ADHKR30M This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy, and if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

Reorient or relocate the receiving antenna Increase the separation between the equipment and receiver Connect the equipment into an outlet on a circuit different from that to which the receiver is connected Consult the dealer or an experienced radio/TV technician for help Additional information on labeling and user information requirements for Part 15 devices can be found in KDB Publication 784748, which is available at the FCC Office of Engineering and Technology (OET) Laboratory Division Knowledge Database (KDB) https://apps.fcc.gov/oetcf/kdb/index.cfm RF Exposure All transmitters regulated by FCC must comply with RF exposure requirements. KDB 447498 General RF Exposure Guidance provides guidance in determining whether proposed or existing transmitting facilities, operations or devices comply with limits for human exposure to Radio Frequency (RF) fields adopted by the Federal Communications Commission (FCC). From the FCC Grant: Output power listed is conducted. This grant is valid only when the module is sold to OEM integrators and must be installed by the OEM or OEM integrators. This transmitter is restricted for use with the specific antenna(s) tested in this application for Certification and must not be co-located or operating in conjunction with any other antenna or transmitters within a host device, except in accordance with FCC multi-transmitter product procedures. These modules are approved for installation into mobile or/and portable host platforms. This module can only be used with a host antenna circuit trace layout design in strict compliance with the OEM instructions provided. Approved Antenna Types To maintain modular approval in the United States, only the antenna types that have been tested shall be used. It is permissible to use a different antenna, provided the same antenna type and antenna gain

(equal to or less than) is used. An antenna type comprises antennas having similar in-band and out-of band radiation patterns. Antennas approved for ATSAMR30M18A module with the antenna types are listed in the section Approved Antennas. Canada The ATSAMR30M18A module has been certified for use in Canada under Innovation, Science, and Economic Development (ISED, formerly Industry Canada) Radio Standards Procedure (RSP) RSP-100, Radio Standards Specification (RSS) RSS-Gen and RSS-247. Modular approval permits the installation of a module in a host device without the need to recertify the device. ATSAMR30M18A has been tested with BPSK-ALT-40, OQPSK-SIN-250 and OQPSK-SIN-1000-SCR-ON PHY modulation modes for ISED modular approval. The user must restrict the PHY modulation mode to the above specified modes for usage in Canada. Labelling and User Information Requirements Labelling Requirements (from RSP-100 - Issue 10, Section 3): The host device shall be properly labelled to identify the module within the host device. Due to the limited module size of ATSAMR30M18A (12.7 mm x 11 mm), the Innovation, Science, and Economic Development Canada certification number identifier is displayed only in the datasheet and packaging box label, and it cannot be displayed on the module. Therefore, the host product must be labelled to display the Innovation, Science and Economic Development Canada certification number of the module, preceded by the word Contains or similar wording expressing the same meaning, as follows:
