1.0 Introduction

The SC14SCMDECT_SFxx_DB Reference Design has

been made available by Dialog Semiconductor B.V.

that includes an additional printed antenna to support

FAD (e.g. for FP operation). This design has obtained a

Modular Approval Certificate (US, EU). When meeting

the conditions as referenced in this document, this

implies that those tests already covered by the Modular

Approval Certificate don’t need to be rerun on the end-

product level. This may alleviate the overall regulatory

approval process of the end-product.

tem level certification process though. Any regulatory standards not covered by the available Modular Approval certificates will still need to be tested on end-product/system level. 2.1 DESCRIPTION When a wireless module has passed the Modular Approval process, and when the host conforms to certain conditions (this will be detailed in the subsequent sections), then the end-product containing this module will not need to be tested against the regulatory standards covered by the module’s certificates.

2.4.5 Le présent émetteur radio (identifier le dispositif par son numéro de certification ou son numéro de modèle s'il fait partie du matériel de catégorie I) a été approuvé par Industrie Canada pour fonctionner avec les types d'antenne énumérés ci-dessous et ayant un gain admissible maximal et l'impédance requise pour chaque type d'antenne. Les types d'antenne non inclus dans cette liste, ou dont le gain est supérieur au gain maximal indiqué, sont strictement interdits pour l'exploitation de l'émetteur.

2.4.6 2.5 MISCELLANEOUS COMMENTS In FCC terminology, a “Host” is what is referred to in DECT as a “fixed part”. The FCC term “Mobile” corresponds with the DECT term “portable part”, provided that the device is >20cm from the human body. A DECT termed “portable part” <20cm from the human body is referred to as “Portable” in FCC terminology. Safety Requirements This section provides of an overview of the safety requirements you must adhere to when working with CVMDECT.

AN-D-212 3.0 External Antenna Design SC14CVMDECT_SFxx_DB External Antenna Design and Leveraging Modular Approval FCC-04-165 now allows different antennas may be certified with one module. Dialog Semiconductor B.V. has obtained Modular Approval for theSC14CVMDECT_SFxx_DB Reference Design using a specific external printed antenna. FCC-04-165 dictates that the certification measurements must to be performed with the highest gain antenna and any other antenna must have a similar radiation pattern.

Printed Antenna Design Details The S11 plot of the SC14CVMDECT_SFxx_DB has been measured (with no 0402 component in Figure 2) and is depicted in the following figure: The printed antenna physical design is shown in Figure 2 (noting the 0.5mm grid in the picture). Figure 4 S11 measurement plot of printed antenna The simulated radiation pattern is depicted in the following plot (with no 0402 component in Figure 2): 3.1.2 Tuning Components For KDECT operation, the frequency band is centered around 1.

If the antenna connected to CVMDECT is user accessible, then the antenna connector shall be proprietary (per FCC DA-00-1407) SC14CVMDECT_SFxx_DB External Antenna Design and Leveraging Modular Approval 3.1.3 DECT_SFxx_DB design and/or if the antenna has a higher gain than that of the SC14CVMDECT_SFxx_DB design, then FCC-04-165 dictates that the Modular Approval is invalidated and that recertification is required on end-product/system level.
