49 / 53 page  4116369 Rev 9.0 September 04, 2017 49 Product Technical Specification Legal Information If a multi-layered PCB is used, the RF path on the board must not cross any signal (digital, analog or supply). If necessary, use StripLine structure and route the digital line(s) "outside" the RF structure. An example of proper routing is shown in the figure below. Stripline and Coplanar design requires having a correct ground plane at both sides. Consequently, it is necessary to add some vias along the RF path. It is recommended to use Stripline design if the RF path is fairly long (more than 3cm), since MicroStrip design is not shielded. Consequently, the RF signal (when transmitting) may interfere with neighbouring electronics (AF amplifier, etc.). In the same way, the neighbouring electronics (micro- controllers, etc.) may degrade the reception performances. The antenna connector is intended to be directly connected to a 50Ω antenna and no matching is needed. 5. A label must be affixed to the outside of the end product into which the HL7548 or HL7588 module is incorporated, with a statement similar to the following: This device contains FCC ID: <FCC ID as listed in the table below> Embedded Module FCC ID HL7548 N7NHL7548 HL7588 N7NHL7588 6. A user manual with the end product must clearly indicate the operating requirements and conditions that must be observed to ensure compliance with current FCC RF exposure guidelines. The end product with an embedded HL7548 or HL7588 module may also need to pass the FCC Part 15 unintentional emission testing requirements and be properly authorized per FCC Part 15. Note: If this module is intended for use in a portable device, you are responsible for separate approval to satisfy the SAR requirements of FCC Part 2.1093. 7.2. IC Statement This device complies with Industry Canada’s license-exempt RSSs. Operation is subject to the following two conditions: 1. This device may not cause interference; and 2. This device must accept any interference, including interference that may cause undesired operation of the device. Le présent appareil est conforme aux CNR d’Industrie Canada applicables aux appareils radio exempts de licence. L’exploitation est autorisée aux deux conditions suivantes: 1. l’appareil ne doit pas produire de brouillage; 2. l’utilisateur de l’appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d’en compromettre le fonctionnement. |
