4 OEM DESIGN CONSIDERATIONS
4.1 RF OUTPUT AND ANTENNA REQUIREMENTS
The RF output / input impedance is 50Ω so the trace leaving from the RF pin shall be kept in that same
impedance level to avoid reflections and mismatch of the RF signal. From the RFID reader module’s point of
view it is important that the used antenna has a low VSWR value. The VSWR shall be better than 1.5:1 in
order to avoid decrease in the sensitivity performance of the receiver because of the TX power reflecting
back from the antenna. In the NUR2-1W module, there is also an automatic leakage cancellation system
that decreases the effect of the reflected signal, and it also improves the isolation of the RX signal from the
TX signal. The automatic leakage cancellation is automatically on when module is operating in normal
mode.
2017-09-07
NUR2-1W HW Implementation Guide v1.0
4.1.1 LAYOUT RECOMMENDATIONS
Figure 4. RF output layout of the reference design.
13
Because NUR2-1W is a wireless device, the RF section must be the top priority in terms of layout. It is very
important that layout is made by following the proper RF design guidelines to get to optimal performance
from the device. Poor layout can decrease the output power, sensitivity and cause mask violations.
Component places; R2, R3 and R12 are for additional output matching. Additional matching is not used in a
reference design. Thus values are as follow: R3 = No assembly, R12 = No assembly and R2 = 100pF 0402
capacitor.
4.1.2 TRANSMISSION LINE
The RF signal from the module is routed to antenna connector using a grounded CPW structure. This is to
achieve the maximum isolation and RF shielding to RF lines. Also GND vias should be added along the line to
give additional shielding.
Figure 5. Grounded CPW with via stitching.

Table 7. Recommended PCB values for 4-layer board (L2 is the GND plane for transmission line)
Parameter Value Unit
W 0.35 mm
S 0.2 mm
H 0.18 mm
Er 4
General recommendations:
1. RF traces must have 50 Ohm impedance because module is only rated to operate in 50 Ohm systems.
2. RF trace bends must be gradual and not have any sharp corners.
3. Grounded CPW structure must have GND via stitching.
4. Only connect antennas which are approved.
4.2 POWER SUPPLY
The NUR2-1W has internal linear power regulators for getting better power supply noise rejection.
14
However, it is still important to supply low noise and stable power to the NUR2-1W module. The voltage
ripple should be kept under 200mVpp and it is recommended to add a minimum of 200µF low ESR, 100nF
and 100pF capacitors next to the VCC_4V0_IN pin.
VCC_3V3_OUT is internal regulator output and it is used for production testing purposes. This pin should
not be used to power external circuits.
4.3 USB DEVICE PORT
USB_DP, USB_DN and USB_5V pins are used to provide 2.0 compliant USB device port. It is advised to use
external ESD protection component if connected to user accessible USB connector. Below is the typical
schematics used with NUR2-1W module.

5 RF PARAMETERS
5.1 TX LEVEL
The maximum output power is +30dBm (1000mW). The power can be adjusted by 1dB steps. In total, there
are 30 steps meaning the minimum output power value is +1dBm that equals to 1mW of power. When
using higher output power levels the antennas VSWR value becomes more and more important factor. High
output power combined with antenna with poor VSWR leads to a situation where significant portion of the
power is reflected back to the receiver.
5.2 RECEIVER SENSITIVITY
2017-09-07
NUR2-1W HW Implementation Guide v1.0
The maximum sensitivity of the module is -81dBm. The receiver can handle +15dBm of power reflecting
back to RF_OUT1 pin without having a big impact on the performance. The receiver architecture uses direct
conversion and it has an integrated AGC (automatic gain controller). Baseband is made using a DSP.
5.3 MODULATION
It is possible to use ASK (amplitude shift keying) or PR-ASK (phase reversed amplitude shift keying)
modulation. Tags that are compliant with ISO18000-6C (EPC C1G2) must support both of these
modulations. The PR-ASK modulation can transfer energy more efficiently to the tag because RF envelope is
high more than it is using ASK modulation. By default the modulation is set to PR-ASK.

5.5 REGION
The NUR2-1W has predefined region settings defining frequency and channel sets for operating under
different radio regulations. Globally the regulations vary depending on the country or part of the world. The
below table shows the available options for the region and the respective frequency band they use. Note
that the antenna also needs to be working on that same frequency.

6 READING PARAMETERS
6.1 Q-VALUE
The Q-value defines the amount of open response slots that tags can use per one inventory round. Number
of slots can be calculated by formula 2Q. It is advised to use twice as much slots compared to amount of tags
that you have in your readers reading field simultaneously. Selectable values are 0 – 15 and value 0 means
automatic Q-value adjustment. When Q=0 is used reader will automatically increase the Q-value when lots
of collisions are noticed and decreased the value when there are only few collisions. By default, the Q-value
is set to 0.

6.2 SESSION
There are four session options which you can use when initializing inventory round. Every session has two
target states A and B. By default, Gen2 tags are at state A if tag has not been read recently. When tag is
read it flips to state B and doesn’t reply to readers query. The table below describes the persistence of tag’s
19
state machine when using different session values. For example, when using session 0 the tag will come
back to state A immediately when tag power is lost. Usually tag loses the power when reader stops the
inventory round or chances the channel. Persistence when tag power is ON is not defined by the ISO18000-
6C when using session settings S0, S2 and S3. With session 1 the tag will keep it state over 500ms but less
than 5s. With session values 2 and 3 tags will keep it states over 2s when tag power is lost. Time can vary
depending what tag IC is used.
2017-09-07
Table 13. Persistence characteristics of gen2 tags.
Flag Persistence: tag power ON Persistence: tag power OFF
S0 indefinite none
S1 500ms < t < 5s 500ms < t < 5s
S2 indefinite t > 2s
S3 indefinite t > 2s
By changing the target setting from A target to B target reader is able to read also tags that has flipped its
state to B state. This would happen if tags would have been read recently using Session 1 2 or 3. NUR2-1W
module also supports dual target mode. In that mode reader will change the target mode between inventory
NUR2-1W HW Implementation Guide v1.0
rounds. By default, target mode A is used.
6.3 ROUNDS
The rounds setting defines how many query rounds is done inside one inventory round. After every
inventory round the reader will send data to the Host. Selectable values are 0 – 10. Zero meaning automatic
rounds adjustment. The automatic adjustment decides after every query round whether another round is
necessary based on the number of data collisions. By default, rounds setting is set to 0. This setting can help
the reader to find all the tags that are in the readers reading field when using session 0. Because tags that
are found in query round 1 doesn’t replay in the following query rounds. When using session 1/2/3 this
does not make any significant difference because tags that are read are quiet anyway.
Table 14. Relation between inventory round and query round.
Round 1 Round 2 round 3 … Round 10
Inventory round
6.4 SELECTING THE RIGHT READING PARAMETERS
One approach is to test how many tags are in the readers reading field simultaneously. Keep the reader still
at the position that is as close to real reading environment as possible and see how many tags are found.
Based on that amount choose your open slot number to be 1.5 – 2 times larger (refer to the section 6.1). If
reader will face many different tag populations auto-Q setting will be a good choice.
20
2017-09-07
Besides Q-value one important parameter is session. In general, it could be stated that if the size of tag
population is measured in thousands rather than in hundreds it is wise to use sessions 2 or 3. Because then
every tag will be read only once and that makes large tag population much faster and easier to read.
Rounds 1 setting is also advised to be used with session 1 or 2 or 3. With session 0 it might be useful to use
higher rounds value than 1 to be able to find all the individual tags. By default, automatic (0) rounds setting
is used.
The selected link profile will have also an effect the read speed.

Session 2/3, auto Q, Rounds 1 over 1 000 over 500
6.5 RSSI FILTERS
NUR2-1W module has internal RSSI filters which can be used to limit the read area. By applying the filters,
you can set the limits which tag replay must met in order to be registered. MIN RSSI –value means that tag
replay signal needs to be equal or stronger then the defined value. Otherwise tag is not read. MAX RSSI
value in other hand means that signal strength must be lower than the filter value.

7 GPIO CONFIGURATIONS
NUR2-1W has 5 programmable GPIOs. All of them can be used as an input or output. They can be also
configured to have different predefined functions.
7.1 INPUT / OUTPUT
All GPIOs can be configured via SW API to be inputs or outputs. IO voltage level is 3.3V and maximum
source current is 4mA and sink current 4mA. When configured as input SW API can check what the state
(high / low) of the GPIO pin is. When GPIO is configured as an output the SW API can drive the GPIO pin to
high or low.

7.2 PREDEFINED FUNCTIONS
Table 16. NUR2-1W module GPIOs options.
RFON (GPIO type: OUTPUT)
When GPIO is configured as “RFON” it drives high state always when power amplifier is turned on. This
function can be used for example driving LED indicator.

Antenna control 1 (GPIO type: OUTPUT)
When GPIO is configured as “antenna control 1” it can be used for controlling external multiplexer on the
Host board to switch between two antennas. Via the SW API it’s possible to select which antennas are
enabled and used or let the module automatically switch between them.

Table 17. 2 Port antenna control truth table.
Case (selected antenna) antenna control 1
0 (antenna 1) low
1 (antenna 2) high
Antenna control 1 & 2 (GPIO type: OUTPUT)
If you want to connect up to 4 antennas and multiplex those using NUR2-1W module you need to configure
2 GPIOs to control the antenna switch. In this case you define one GPIO to be “antenna control 1” and
second one to be “antenna control 2”. Via the SW API it’s possible to select which of the connected
antennas are enabled and used or let the module automatically switch between them.

8 DIAGNOSTIC FUNCTIONS
8.1 REFLECTED POWER MEASUREMENTS
This measurement can be used to check what is the matching of the antenna(s) and feed line(s). When this
function is triggered will NUR2-1W module put carrier wave ON at full power and then measure the
absolute power level that is coming to receiver port. There is a fixed difference in actual reflected power
level and the level reported by the module. You can calculate the real reflected power level using below
formula:
Reflected power level = (Reported reflected power level by the module) +(25)
8.2 CHANNEL SCANNER (TBD)
TBD
.
24
8.3 RECEIVED SIGNAL STRENGTH (RSSI)
When reading a tag NUR2-1W module also returns received signal strength indication values if wanted. Two
values are returned per one tag. One is the absolute power level (dBm) and second is the scaled power level
value of the tags backscatter signal. Scaled RSSI value is 0 – 100.

10 SMT ASSEMBLY PROCESS AND THERMAL PROCESSING
NUR2-1W module contains single sided assembly of SMT components reflow-soldered on multilayer HDI
(high density interconnections) glass-fiber re-enforced epoxy printed board. The bottom side terminations
are ENIG (NiP/Au) plated. Soldering alloy used for attaching module components is eutectic SnAgCu.
Module internal components soldering has been optimized for minimal thermal stress.
NUR2-1W modules shall be delivered in a special tray packing to protect modules against mechanical, ESD
and moisture related stresses. Due to high density interconnections technology, module total water content
has to be below 0.1%-w prior to any thermal processing above water boiling point.
2017-09-07
The board assembly process of NUR module on motherboard will introduce re-flow of module components.
Thus, to avoid degradation of solder joint interfaces, the module has to be stored and soldered according to

11.2 FCC
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
2017-09-07
NUR2-1W HW Implementation Guide v1.0
interference by one of the following measures:
Reorient or relocate the receiving antenna.
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.
This 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 operation.
Note
User of the module cannot change the region setting of the module. When FCC region is set, the
module operates in frequency band of 902 – 928Mhz.
FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance
39
could void the user's authority to operate this equipment.
This NUR2-1W transmitter module is authorized to be used in other devices only by OEM Integrators under
the following conditions:
1. The module can be used only with the approved antenna types (see the section of Approved antennas
below) having the antenna gains of 5dBi and 6dBi at the maximum. The approved antennas need the
following minimum separation distances when installed:

NUR2-1W HW Implementation Guide v1.0
Product Uncontrolled/general population Occupational / controlled environments
NUR2-1W + antenna with
5dBi max. gain

22.8cm separation distance @915MHZ
RF exposure evaluation is not required at
20cm separation distance @915MHZ
RF exposure evaluation is not required at
20cm separation distance @915MHZ
Table 11.2.1
Note. The antenna must be installed such that the minimum separation distance can be maintained between the
antenna (radiator) and user’s/nearby people’s body at all times.
If the antenna being one of the approved antenna types has lower antenna gain than the type’s maximum
one, the minimum separation distance (d in cm) can be calculated by giving the EIRP (in mW) of the
configuration and the maximum permissible exposure (S = 0.61 mWcm-2) to the following formula: d =
√(EIRP/(4πS)). However, despite the fact that the result of the calculation can be below 20 cm, the
separation distance of 20 cm is always the minimum.
The EIRP (EIRP
= Po - Ll + G ) needed for the calculation of minimum separation distance consists of the
dBm
following factors:
Po = (Maximum peak output of NUR2-1W transmitter + measurement uncertainty) = + (dBm)
Ll = (Line losses) = known value (dB)
G = (Antenna gain) = known value (dBi)
2. The transmitter module must not be co-located with any other transmitter, except with those that are
within the limits shown in the NUR2-1W filing.
3. The transmitter module can only be used with a host antenna circuit trace layout design in strict
compliance with the OEM instructions provided.
When the conditions above are met, typically no radio transmitter testing of NUR2-1W is required.
However, the OEM integrators have responsibility for testing their end-product for other compliance
requirements, for example digital device emissions, PC peripheral requirements.
The antenna used with the NUR2-1W transmitter module shall comply with the gain limit of 6 dBi. The
antennas having higher gain may be used, if cable loss compensates the exceeded antenna gain. For
example, 2dB antenna cable loss reduces the EIRP of the configuration so that 8dBi antenna may be used. If
40
the cable loss does not cancel out the exceeded gain then the transmitter’s conducted output power shall
be reduced so that the EIRP of the configuration is kept inside the limits of 4W.
Note.
In the event that these conditions can’t be met (for certain configurations or co-location with another
transmitter), then the FCC authorization is no longer considered valid and the FCC ID can’t be used on the
final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end
product (including the transmitter) and obtaining a separate FCC authorization.
The OEM integrator must be aware not to provide information to the end user regarding how to install or
remove this RF module in the user manual of the end product.
For the User’s Guide the required FCC statements outlined in the User’s Guide Requirements section must
be in a prominent location.
USER’S GUIDE REQUIREMENTS
2017-09-07
NUR2-1W HW Implementation Guide v1.0
The texts in quotation marks below are the required FCC statements in the user’s guide. The note given in
brackets is not an FCC statement but it gives the required information on the first required FCC statement.
“To comply with FCC’s RF radiation exposure requirements in general population environment, the
antenna(s) used for this transmitter must be installed such that a minimum separation distances of ‘d’ cm
(shown in table 11.2.1) is maintained between the radiator (antenna) & user’s/nearby people’s body at all
times and must not be co-located or operating in conjunction with any other antenna or transmitter.”
(Note: Use the following formula to find the ‘d’ in cm: d = √(EIRP/(4πS)); let ‘EIRP’ have the maximum EIRP
(in mW) of your transmitter configuration, and let ‘S’ have the 0.61 (in mW/cm2) value. In addition, the ‘d’
value cannot be below separation distances shown in table 11.2.1, although the formula would yield
smaller minimum separation distance d. See also the EIRP factors mentioned above.)
“To comply with FCC’s RF radiation exposure requirements in controlled environment, the antenna(s) used
for this transmitter must be installed such that a minimum separation distances of ‘d’ cm (shown in table
41
11.2.1) is maintained between the radiator (antenna) & user’s/nearby people’s body at all times and must
not be co-located or operating in conjunction with any other antenna or transmitter.”
(Note: Use the following formula to find the ‘d’ in cm: d = √(EIRP/(4πS)); let ‘EIRP’ have the maximum EIRP
(in mW) of your transmitter configuration, and let ‘S’ have the 3.050 (in mW/cm2) value. In addition, the ‘d’
value cannot be below separation distances shown in table 11.2.1, although the formula would yield
smaller minimum separation distance d. See also the EIRP factors mentioned above.)

2017-09-07
NUR2-1W HW Implementation Guide v1.0
To leverage the Nordic ID’s IC grant, the device with the integrated NUR2-1W module shall be met the
following conditions:
1. The antennas being the approved types with the maximum gain of 5dBi and of 6dBi shall be installed so
that the device’s user or nearby people or passing people cannot compromise the minimum separation
distances shown in table 11.3.1, respectively, in any situation.
If the antenna being one of the approved antenna types has lower antenna gain than the type’s
maximum one, the minimum separation distance in general public environment (d in cm) can be
calculated by giving the EIRP of the configuration and the exposure limit (S = 0.276 mWcm2) to the
following formula: d = √(EIRP/(4πS)).
For controlled environment (d in cm) can be calculated by giving the EIRP of the configuration and the
exposure limit (S = 0.629 mWcm-2) to the following formula: d = √(EIRP/(4πS)).

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 radioélectrique
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 communication satisfaisante..
Le module émetteur NUR2-1W estautorisé à êtreutilisé avec d’autresappareilsuniquement par des
intégrateurs OEM sous les conditions suivantes :
1. Les antennes étant les types approuvés avec le gain maximal de 5dBi et de 6dBi doivent être installés de
