AN-D-211 External Antenna Design and Leveraging Modular Approval for CVMDECT© 2013 Dialog Semiconductor B.V. Company Confidential 2 June 28, 2013 v0.22.0 Modular Approval2.1 DESCRIPTIONWhen a wireless module has passed the ModularApproval process, and when the host conforms to cer-tain conditions (this will be detailed in the subsequentsections), then the end-product containing this modulewill not need to be tested against the regulatory stand-ards covered by the module’s certificates. The availability of the Modular Approval is intended toreduce time, cost and effort putting an end-productcontaining CVMDECT on the market.2.2 AVAILABLE CERTIFICATIONSDialog Semiconductor B.V. has obtained the followingmodular approvals for CVMDECT:• FCC Part 15, subpart D, Isochronous UPCS Device 1920-1930 MHz: FCC ID Y82-SC14D• IC RSS-213, issue 2, 2GHz License-exempt Per-sonal Communications Service Devices: IC ID 9576A-SC14DIn addition, testing has shown compliance to the follow-ing:• EU testing (to be used in the DoC process when applicable:• Emissions EN 301-406• Immunity EN 301-489• CE IECEN 60950-1• SAR EN 62311• JP Radio Law pre-test2.3 APPLICABILITYOnly FCC (US) and IC (Canada) officially support Mod-ular Certification. ETSI (Europe) doesn’t supports Modular Certification,rather Declaration of Conformity (DoC). The manufac-turer is responsible for the compliance to regulatoryrequirements. Previous testing, such as made availa-ble by Dialog Semiconductor B.V., may be taken intoconsideration by the module integrator. If module test-ing is trusted for the DoC of the host, the module’sTechnical Construction File (TCF) becomes part of thehost’s TCF.This is part of the “self certification” process where theend-product OEM declares conformity to regulatoryrequirements. The available ETSI test reports may beused to this purpose and the tests in these reportsdon’t need to be repeated on end-product/system level.MIC (Japan) announced incorporation of modularapprovals in Japanese Radio Law (Feb ‘13). Require-ments are being developed now. Currently, there is notimeline or estimated implementation date. ModularCertification is still judged on a case-by-case basis. Other countries may not support Modular Certification.The available test reports may help expedite the sys-tem level certification process though.Any regulatory standards not covered by the availableModular Approval certificates will still need to be testedon end-product/system level.2.4 CONDITIONSThe FCC document “DA-00-1407” provides a clearoverview of the conditions applicable to the host, asso-ciated with leveraging existing Modular Approval. With respect to CVMDECT, the following subsectionsreference the relevant conditions that have to be met.Not adhering to these will invalidate the certification,requiring recertification on end-product/system level.2.4.1 AntennaThe FCC document “DA-00-1407” specifies:• The antenna gain of a new antenna should be of the same type as the originally approved antenna and the antenna gain should not be higher than the antenna gain of the originally tested antenna. • The emission levels or reported RF safety levels shall not be increased by the new antenna (of the same antenna type) • If the new antenna is a different type, recertification on end-product/system level is required.With the existing CVMDECT certification this impliesthe following:• If only the embedded/internal antenna of CVMDECT is used, then the Antenna Condition is fulfilled• If an external antenna is connected to CVMDECT, then this antenna would need to meet specific crite-ria in order to prevent recertification requirements. Please refer to section 3.0 for further details.2.4.2 Transmitter AntennaUnder Industry Canada regulations, this radio transmit-ter may only operate using an antenna of a type andmaximum (or lesser) gain approved for the transmitterby Industry Canada. To reduce potential radio interfer-ence to other users, the antenna type and its gainshould be so chosen that the equivalent isotropicallyradiated power (e.i.r.p.) is not more than that neces-sary for successful communication.Conformément à la réglementation d'Industrie Canada,le présent émetteur radio peut fonctionner avec uneantenne d'un type et d'un gain maximal (ou inférieur)approuvé pour l'émetteur par Industrie Canada. Dansle but de réduire les risques de brouillage radioélectri-que à l'intention des autres utilisateurs, il faut choisir letype d'antenne et son gain de sorte que la puissanceisotrope rayonnée équivalente (p.i.r.e.) ne dépasse pasl'intensité nécessaire à l'établissement d'une communi-cation satisfaisante.Under Industry Canada regulations, this radio transmit-ter may only operate using an antenna of a type andmaximum (or lesser) gain approved for the transmitter
AN-D-211 External Antenna Design and Leveraging Modular Approval for CVMDECT© 2013 Dialog Semiconductor B.V. Company Confidential 3 June 28, 2013 v0.2by Industry Canada. To reduce potential radio interfer-ence to other users, the antenna type and its gainshould be so chosen that the equivalent isotropicallyradiated power (e.i.r.p.) is not more than that neces-sary for successful communication.Le présent émetteur radio (identifier le dispositif parson numéro de certification ou son numéro de modèles'il fait partie du matériel de catégorie I) a été approuvépar Industrie Canada pour fonctionner avec les typesd'antenne énumérés ci-dessous et ayant un gainadmissible maximal et l'impédance requise pourchaque type d'antenne. Les types d'antenne non inclusdans cette liste, ou dont le gain est supérieur au gainmaximal indiqué, sont strictement interdits pourl'exploitation de l'émetteur.2.4.3 Host PCB layoutThe PCB layout of the host PCB is critical to the validityof the RF certification of CVMDECT because it is partof the embedded printed antenna. Please refer to sec-tions 7.4 and 7.5 of the SC14CVMDECT SFxx data-sheet for details.2.4.4 Labelling RequirementsFCCThe modular transmitter must be labelled with its ownFCC ID number. If the FCC ID is not visible when themodule is installed inside another device, then the hostdevice must contain the FCC ID number with the state-ment such as the following: "Contains FCC ID: Y82-SC14D".Some further details about labelling requirements andcompliance statements can be found in "784748 D01Labelling Part 15 18 Guidelines v07". IC (Canada)The host device shall be properly labelled to identifythe modules within the host device. The Industry Can-ada certification label of a module shall be clearly visi-ble at all times when installed in the host device,otherwise the host device must be labelled to displaythe Industry Canada certification number of the mod-ule, preceded by the words “Contains transmitter mod-ule”, or the word “Contains”, or similar wordingexpressing the same meaning, as follows:Contains transmitter module IC: 9576A-SC14DL'appareil hôte doit être étiqueté comme il faut pourpermettre l'identification des modules qui s'y trouvent.L'étiquette de certification d'Industrie Canada d'unmodule donné doit être posée sur l'appareil hôte à unendroit bien en vue en tout temps. En l'absence d'éti-quette, l'appareil hôte doit porter une etiquette donnantle numéro de certification du module d'Industrie Can-ada, précédé des mots « Contient un module d'émis-sion », du mot « Contient » ou d'une formulationsimilaire exprimant le même sens, comme suit :Contient le module d'émission IC: 9576A-SC14D2.4.5 User Documentation TextThe literature provided to the end user must include thefollowing wording:“FCC compliance statementThis device complies with Part 15 of the FCC Rules.Operation is subject to the following two conditions:(1) this device may not cause harmful interference, and(2) this device must accept any interference received,including interference that may cause undesired opera-tion of the device.Module transmetteur ID IC:This device complies with Industry Canada licence-exempt RSS standard(s).

Company Confidential 4 June 28, 2013 v0.2ITE Class: CAN ICES-3 (B)/NMB-3(B). 2.4.6 Safety RequirementsThis section provides of an overview of the safetyrequirements you must adhere to when working withCVMDECT.• The specific external power supply for CVMDECT has to fulfil the requirements according to clause 2.5 (Limited power source) of this standard EN 60950-1:2006.• Interconnection circuits shall be selected to provide continued conformance to the requirements of clause 2.2 for SELV (Safety Extra Low Voltage) cir-cuits according to EN 60950-1:2006 after making connections• Interface type not subjected to over voltages • Requirements additional to those specified in this standard may be necessary for:• Equipment intended for operation in special envi-ronments (for example, extremes of temperature, excessive dust, moisture or vibration, flammable gases and corrosive or explosive atmospheres)• Equipment intended to be used in vehicles, on board ships or aircraft, in tropical countries or at altitudes greater than 2000m• Equipment intended for use where ingress of water is possible• Installation by qualified personnel only• The product is a component intended for installation and use in complete equipment. The final accept-ance of the component is dependent upon its instal-lation and use in complete equipment2.5 MISCELLANEOUS COMMENTSIn FCC terminology, a “Host” is what is referred to inDECT as a “fixed part”. The FCC term “Mobile” corre-sponds with the DECT term “portable part”, providedthat the device is >20cm from the human body. ADECT termed “portable part” <20cm from the humanbody is referred to as “Portable” in FCC terminology.The antenna(s) used for this transmitter must beinstalled to provide a separation distance of at least 20cm from all persons and must not be co-located oroperating in conjunction with any other antenna ortransmitter.Une distance de séparation de 20cm ou plus doit êtremaintenue entre cet appareil et des personnes lors defonctionnement du dispositif. L’antenne utilisée pour cetransmetteur ne doit pas être co-localisés en conjonc-tion avec toute autre antenne ou transmetteur.A Permissive Change to the Modular Approval canonly be issued by the Grantee (i.e. Dialog Semiconduc-tor B.V.). Therefore, any change to the module and/orits connections will require submission for a new FCCID by the customer (either on module level or systemlevel).The existing Modular Approval may be invalidated ifCVMDECT is co-located with other wireless devices(e.g. BlueTooth, WLAN/WiFi) that transmit simultane-ously. Please consult with your test house on the possi-ble implications.
AN-D-211 External Antenna Design and Leveraging Modular Approval for CVMDECT© 2013 Dialog Semiconductor B.V. Company Confidential 5 June 28, 2013 v0.23.0 External Antenna DesignFCC-04-165 now allows different antennas may becertified with one module. Dialog Semiconductor B.V.has obtained Modular Approval for CVMDECT using aspecific external printed antenna. FCC-04-165 dictatesthat the certification measurements must to be per-formed with the highest gain antenna and any otherantenna must have a similar radiation pattern. For CVMDECT, this implies that an external antennamay be connected to radio module, provided that:• the antenna gain is not higher than -1.2dBi• the antenna type is a (printed) monopoleIn addition, if the antenna connection is user accessi-ble, then the antenna connector shall be proprietary.3.1 SC14CVMDECT_AF01_SF01 CONVERSION BOARDThe “SC14CVMDECT_AF01_SF01” design is a con-version PCB that holds a SC14CVMDECT SF xx mod-ule on the top side, while having an SC14CVMDECTAF compatible footprint on the bottom side. Pleaserefer to the following indicative picture:Figure 1 SC14CVMDECT_AF01_SF01 with SC14CVMDECT SFxx moduleThis design also has an embedded printed antenna(located to the top right in the above picture) so thatCVMDECT can support FAD and may have increasedperformance to operate as an FP.The SC14CVMDECT_AF01_SF01 design passed theModular Approval testing and can be used as a drop-inreplacement for the SC14CVMDECT AF module with-out needing to recertify the end-product (for thosecountries allowing Modular Approvals, please refer tosection 2.3).The gerber files of this design can be obtained throughyour Dialog Semiconductor B.V. sales contact or repre-sentative.3.1.1 Boundary ConditionsIn order to be allowed to leverage the CVMDECT Mod-ular Approval for the SC14CVMDECT_AF01_SF01design, the PCB should meet the following specifica-tions:• PCB material: FR4 • Dimensions: length x width x thickness = 25.9mm x 25.0mm x 0.8mm• PCB layer stackup:• L1 copper thickness: 18um• L1-L2 prepreg thickness: 163um• L2 copper thickness: 35um• L2-L3 core thickness: 360um• L3 copper thickness: 35um• L3-L4 prepreg thickness 163um• L4 copper thickness: 18umThe SC14CVMDECT_AF01_SF01 has been designedusing 6mil lines/space and 0.25mm end-size drill holesrules.When deviating in any way from these specifications,the Modular Approval will be invalidated and recertifi-cation on end-product/system level will be required.
AN-D-211 External Antenna Design and Leveraging Modular Approval for CVMDECT© 2013 Dialog Semiconductor B.V. Company Confidential 6 June 28, 2013 v0.23.2 HOST PCB PRINTED ANTENNA DESIGNThe printed antenna that is part of the SC14CVM-DECT_AF01_SF01 design can also be used directly,as part of the host PCB design.In that case, the host PCB design must adhere to thesame PCB layer stackup (material, layer spacings) asmentioned in section 3.1.1. The antenna must belocated in a corner and spaced from the SC14CVM-DECT SFxx module in the same way as theSC14CVMDECT_AF01_SF01 design. Also the groundplane design (especially the spacing with respect to theantenna structure) should follow exactly the same out-line as in the SC14CVMDECT_AF01_SF01 design.The printed antenna is not 50 Ohms by itself. Itrequires a printed transformer on the inner layer (indi-cated in red in the below picture) that is part of theSC14CVMDECT_AF01_SF01 design. The layout ofthis component is critical to the antenna performanceand should be copied accurately from the availablegerber files.Figure 2 SC14CVMDECT_AF01_SF01 printed antenna design detailsFigure 2 here above is only meant to show the basicdesign; the picture is from simulation used as a basisfor the actual physical design. The gerber files shouldbe leading in any customer design.3.3 OTHER ANTENNASIf an antenna is connected to CVMDECT that has adissimilar radation pattern than that of the SC14CVM-DECT_AF01_SF01 design and/or if the antenna has ahigher gain than that of the SC14CVM-DECT_AF01_SF01 design, then FCC-04-165 dictatesthat the Modular Approval is invalidated and that recer-tification is required on end-product/system level.If the antenna connected to CVMDECT is user acces-sible, then the antenna connector shall be proprietary(per FCC DA-00-1407).
