Introduction
1.4 DISCLAIMER
This document is for general information purposes
only. Dialog Semiconductor B.V. does not guarantee
the completeness, correctness or accuracy of the information in this document and shall not be liable for any
direct or indirect loss or damage arising from the use of
information or documents found in it.
The SC14SCMDECT_SFxx_DB Reference Design has
been made available by Dialog Semiconductor 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 endproduct level. This may alleviate the overall regulatory
approval process of the end-product.

SC14CVMDECT External Antenna Design and Leveraging Modular Approval
Modular Approval
Other countries may not support Modular Certification.
The available test reports may help expedite the system level certification process though.
2.1 DESCRIPTION
When a wireless module has passed the Modular
Approval process, and when the host PCB design 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.
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, associated with leveraging existing Modular Approval.
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
limited modular approvals for CVMDECT:
With respect to the SC14CVMDECT_SFxx_DB Reference Design, 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.
• FCC Part 15, subpart D, Isochronous UPCS Device
1920-1930 MHz: FCC ID Y82-SC14D
2.4.1 Antenna
The FCC document “DA-00-1407” specifies:
• IC RSS-213, issue 2, 2 GHz License-exempt Personal Communications Service Devices:
IC ID 9576A-SC14D
• 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.
• In addition, testing has shown compliance to the following:
• The emission levels or reported RF safety levels
shall not be increased by the new antenna (of the
same antenna type)
• EU testing (to be used in the DoC process when
applicable:
• Emissions EN 301-406
• If the new antenna is a different type, recertification
on end-product/system level is required.
• Immunity EN 301-489
• CE IECEN 60950-1
With the existing SC14CVMDECT_SFxx_DB certification this implies the following:
• SAR EN 62311
• If only the embedded/internal antenna of CVMDECT
is used, then the Antenna Condition is fulfilled
• JP Radio Law pre-test
2.3 APPLICABILITY
Only FCC (US) and IC (Canada) officially support Modular Certification.
• If an external antenna is connected to CVMDECT,
then this antenna would need to meet specific criteria in order to prevent recertification requirements.
Please refer to section 3.0 for further details.
ETSI (Europe) doesn’t supports Modular Certification,
rather Declaration of Conformity (DoC). The manufacturer is responsible for the compliance to regulatory
requirements. Previous testing, such as made available by Dialog Semiconductor B.V., may be taken into
consideration by the module integrator. If module testing is trusted for the DoC of the host, the module’s
Technical Construction File (TCF) becomes part of the
host’s TCF.
2.4.2 Host PCB Layout
The PCB layout of the host PCB is critical to the validity
of the RF certification of CVMDECT because it is part
of the embedded printed antenna. Please refer to sections 7.4 and 7.5 of the SC14CVMDECT SFxx datasheet for details.
2.4.3 Labelling Requirements
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.
The modular transmitter must be labelled with its own
FCC ID number. If the FCC ID is not visible when the
module is installed inside another device, then the host
device must contain the FCC ID number with the statement such as the following:
"Contains FCC ID:Y82-SC14D",
“Contains IC ID:9576A-SC14D”.
MIC (Japan) announced that it would allow modular
approvals in Japanese Radio Law (Feb ‘13). Requirements are being developed now. Currently, there is no
timeline or estimated implementation date. Modular
Certification is still judged on a case-by-case basis.
Application Note
CFR0014-01
Some further details about labelling requirements and
compliance statements can be found in "784748 D01
Labelling Part 15 18 Guidelines v07".

“FCC compliance statement
• Equipment intended for operation in special environments (for example, extremes of temperature,
excessive dust, moisture or vibration, flammable
gases and corrosive or explosive atmospheres)
Module transmetteur ID IC:
Son fonctionnement est soumis aux deux conditions
suivantes:
(1) cet appareil ne doit pas causer d’interférences nuisibles et
• Equipment intended to be used in vehicles, on

altitudes greater than 2000 m
(2) appareil doit accepter toute interference recue, y
compris les interferences qui peuvent pertuber le fonctionnement.
• Equipment intended for use where ingress of
water is possible
• Installation by qualified personnel only
Changes or modifications to the equipment not
expressly approved by the Party responsible for compliance could void the user's authority to operate the
equipment.
• The product is a component intended for installation
and use in complete equipment. The final acceptance of the component is dependent upon its installation and use in complete equipment
NOTE: This equipment has been tested and found to
comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against
harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there
is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or more of the following measures:
2.5 SAR
Because SAR is very device-specific, FCC rules do not
allow for a (Limited) Modular Approval for use with portable devices (i.e. devices <20 cm from the human
body).
If time-averaged output power is <60/f(GHz) mW or all
measured 1-g SAR are <0.4 W/kg then modular
approval may still be allowed for portable devices.
Please refer to FCC document “D01 Mobile Portable
RF Exposure v04”.
SAR test reports are available as a reference, showing
compliance to regulatory requirements (with respect to
Portable Equipment).
• Reorient or relocate the receiving antenna
2.6 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 >20 cm from the human body. A
DECT termed “portable part” <20 cm from the human
body is referred to as “Portable” in FCC terminology.
• Increase the separation between the equipment and
receiver
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
Privacy of communications may not be ensured when
using this phone.”
The existing Modular Approval may be invalidated if
CVMDECT is co-located with other wireless devices
(e.g. BlueTooth, WLAN/WiFi) that transmit simultaneously. Please consult with your test house on the possible implications.
2.4.5 Safety Requirements
This section provides of an overview of the safety
requirements you must adhere to when working with
CVMDECT.
• The specific external power supply for CVMDECT
has to fulfil the requirements according to clause 2.5

SC14CVMDECT External Antenna Design and Leveraging Modular Approval
External Antenna Design
3.1.1 Printed Antenna Design Details
The printed antenna physical design is shown in Figure
2 (noting the 0.5 mm grid in the picture).
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.
In case of the SC14CVMDECT_SFxx_DB certification,
this implies that an external antenna may be connected
to radio module, without requiring recertification, provided that:
• the antenna gain is not higher than 0 dBi
• the antenna type is a (printed) monopole
In addition, if the antenna connection is user accessible, then the antenna connector shall be proprietary.
3.1 SC14CVMDECT_SFXX_DB ANTENNA DESIGN
The SC14CVMDECT_SFxx_DB Reference Design
includes a SC14CVMDECT SFxx module and an additional printed antenna to support FAD (e.g. to operate
as an FP).
Figure 2: Printed Antenna Physical Structure
The simulated radiation pattern is depicted in the following plot (with no 0402 component in Figure 2):
Figure 1: SC14CVMDECT_SFxx_DB Reference
Design Overiew
In Figure 1 an overview is given of the
SC14CVMDECT_SFxx_DB Reference Design. In the
middle right section the SF module can be seen. The
printed antenna occupies the lower right part in Figure
1.
Figure 3: Simulated Radiation Pattern
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:
This Reference Design is an example application
design. The key part of this design, in relation to wireless performance and leveraging existing Modular
Approval, is the section of the printed antenna in the
lower right corner, together with its location and connection with respect to the SF module, as well as the
ground plane contours. This relevant section is highlighted by the light green rectangle in Figure 1.
The gerber files of this design can be obtained through
your Dialog Semiconductor sales contact or representative.

SC14CVMDECT External Antenna Design and Leveraging Modular Approval
One important note with respect to KDECT operation:
though the printed antenna design can be made to
operate at 1.8 GHz, the embedded antenna that is part
of the SC14CVMDECT_SFxx module would remain
centred at 1.9 GHz since there are no external tuning
components to alter the resonant frequency of the
CS14CVMDECT_SFxx embedded antenna. This
implies antenna design should be selected for operation. This would limit the applicability to PP mode operation.
3.1.3 Boundary Conditions
In order to be allowed to leverage the CVMDECT Modular Approval for the SC14CVMDECT_SFxx_DB
design, the PCB should meet the following specifications:
• PCB material: FR4
Figure 4: S11 Measurement Plot of Printed
Antenna
• PCB layer stackup:
• L1 copper thickness: 18 m
3.1.2 Printed Antenna Design Operating at 1.8 GHz
• L1-L2 prepreg thickness: 360 m (2x “Prepreg
7628”)
For KDECT operation, the frequency band is centred
around 1.8 GHz, whereas the default printed antenna
design configuration is designed to be centred around
1.9 GHz. The printed antenna design holds a provision
for this shift in operating frequency.
• L2 copper thickness: 35 m
• L2-L3 core thickness: 710 m
• L3 copper thickness: 35 m
Please refer to Figure 2. If a 100 pF capacitor (0402
footprint) is placed across the gap indicated by the
green ellipse indicated in Figure 2, then effectively the
antenna length is increased resulting in resonant frequency of 1.8 GHz (without the 100 pF 0402 components, the antenna’s resonant frequency remains at
1.9 GHz for other DECT operation). No other tuning
components are required.
• L3-L4 prepreg thickness 360 m (2x “Prepreg
7628”)
• L4 copper thickness: 18 m
In addition, it is imperative that the physical design of
the printed antenna is accurately copied. Also the contours of the ground plane surrounding the printed
antenna must be accurately copied. The printed
antenna location should be the same (i.e. in a corner
with the same orientation/spacing with respect to the
SF module).
When deviating in any way from these specifications,
the Modular Approval will be invalidated and recertification on end-product/system level will be required.
3.2 TUNING COMPONENTS
The printed antenna design tuning has been validated
and found to require a resistive -attenuator network to
keep spurious emissions within ETSI limit.
It should be also noted that the printed antenna
design’s impedance is a short at DC. So a coupling
capacitor
is
required
to
connect
the
SC14CVMDECT_SFxx module to the printed antenna
design.
Figure 5: Printed Antenna Design S11 Plot in
KDECT Mode
The
S11
plot
(measured
on
the
actual
SC14CVMDECT_SFxx_DB Reference Design HW)
with the printed antenna design configured in KDECT
mode (i.e. with 100 pF 0402 component placed across
the length extension gap) is depicted in the Figure 5.

3.3 OTHER ANTENNAS
If an antenna is connected to CVMDECT that has a
dissimilar radiation pattern than that of the
SC14CVMDECT_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.
If the antenna connected to CVMDECT is user accessible, then the antenna connector shall be proprietary
(per FCC DA-00-1407)
