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.
