The radio transmitter has been approved by Industry Canada to operate with the
antenna types listed above with the maximum permissible gain and required antenna
impedance for each antenna type indicated. Antenna types not included in this list
having a gain greater than the maximum gain indicated for that type, are strictly
prohibited for use with this device.
Cet ѐmetteur de radio a ѐtѐ approuvѐ par Industrie Canada pour fonctionner avec les
types d’antennes ѐnumѐrѐes ci-dessus avec le gain maximal admissible et impѐdance
d’antenna requise pour chaque type d’antenne indiquѐ. Types d’antennes ne figurant
pas dans cette liste, ayant un gain supѐrieur au gain maximum indiquѐ pour ce type,
sont strictement interdites pour l’utilisation avec cet appareil.Inventek is obtaining FCC, IC,
and CE modular transmitter certifications for the ISM4343-WBM-L151 Module. These
certifications can be used to the advantage of any manufacturer developing a product using
these devices. In order to take full advantage of the certifications, developers must follow the
antenna design/layout guidelines exactly as shown in the datasheet. For FCC compliance,
products will still need to go through verification testing or have a declaration of conformance
according to 47 CFR Chapter 1, part 15, subpart B.
The testing required for both verification and declaration of conformance is specified in sections
15.107 and 15.109. The official documents can be obtained from the U.S Government Printing
Office online. U.S. Government Printing Office CFR 47. There are some changes allowed to the
reference design which do not require any testing beyond the verification or declaration of
conformance.
If it is desired to add a connector or U.FL connector in the RF path, or change the antenna to
one of the same types (chip) with equal or less gain, they can do so without refiling. Other
changes such as a different antenna, or adding an antenna diversity switch will require filing
for a class 2 permissive change. Any class 2 permissive changes must be performed under
Inventek’s grant, and therefore must be done in cooperation with Inventek. In addition to this
document, Inventek recommends verifying the schematic board design with Inventek
Engineering once the schematic is complete for further review and validation.
