AN-D-211 External Antenna Design and Leveraging Modular Approval for CVMDECT
© 2013 Dialog Semiconductor B.V. Company Confidential 2 June 28, 2013 v0.2
2.0 Modular Approval
2.1 DESCRIPTION
When a wireless module has passed the Modular
Approval process, and when the host conforms to cer-
tain 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 stand-
ards covered by the module’s certificates.
The availability of the Modular Approval is intended to
reduce time, cost and effort putting an end-product
containing CVMDECT on the market.
2.2 AVAILABLE CERTIFICATIONS
Dialog Semiconductor B.V. has obtained the following
modular 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-SC14D
In 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-test
2.3 APPLICABILITY
Only 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 regulatory
requirements. Previous testing, such as made availa-
ble by Dialog Semiconductor B.V., may be taken into
consideration by the module integrator. If module test-
ing is trusted for the DoC of the host, the module’s
Technical Construction File (TCF) becomes part of the
host’s TCF.
This is part of the “self certification” process where the
end-product OEM declares conformity to regulatory
requirements. The available ETSI test reports may be
used to this purpose and the tests in these reports
don’t need to be repeated on end-product/system level.
MIC (Japan) announced incorporation of modular
approvals in Japanese Radio Law (Feb ‘13). Require-
ments are being developed now. Currently, there is no
timeline or estimated implementation date. Modular
Certification 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 available
Modular Approval certificates will still need to be tested
on end-product/system level.
2.4 CONDITIONS
The FCC document “DA-00-1407” provides a clear
overview of the conditions applicable to the host, asso-
ciated with leveraging existing Modular Approval.
With respect to CVMDECT, the following subsections
reference 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 Antenna
The 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 implies
the 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 Antenna
Under Industry Canada regulations, this radio transmit-
ter may only operate using an antenna of a type and
maximum (or lesser) gain approved for the transmitter
by Industry Canada. To reduce potential radio interfer-
ence to other users, the antenna type and its gain
should be so chosen that the equivalent isotropically
radiated 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 une
antenne d'un type et d'un gain maximal (ou inférieur)
approuvé pour l'émetteur par Industrie Canada. Dans
le but de réduire les risques de brouillage radioélectri-
que à l'intention des autres utilisateurs, il faut choisir le
type d'antenne et son gain de sorte que la puissance
isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas
l'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 and
maximum (or lesser) gain approved for the transmitter
