2019-03-08 NUR-0W1 HW implementation guide CONFIDENTIAL Version 1.0 4. OEM DESIGN CONSIDERATIONS When integrating the NUR-0W1 module into host board you need to follow the below recommendations to obtain proper operation of the module. 4.1. RF-OUTPUT AND ANTENNA REQUIREMENTS For UHF RFID module it is very important that good RF design practices are used. Unlike conventional radios, transmission and receiving are on at the same time without significant frequency separation.
2019-03-08 NUR-0W1 HW implementation guide CONFIDENTIAL Version 1.0 Profile Value Units W 0.35 mm S 0.2 mm H 0.18 mm Er 4 4.2. POWER SUPPLY The NUR-0W1 has internal linear power regulators for getting better power supply noise rejection. However, it is still important to supply low noise and stable power to the module. The voltage ripple should be kept under 200mVpp and it is recommended to add a minimum of 100µF low ESR, 100nF and 100pF capacitors next to the VCC_3V6_IN pin.
2019-03-08 NUR-0W1 HW implementation guide CONFIDENTIAL Version 1.0 than 1 antenna and antenna switch is controlled by NUR-0W1 antenna control -functions, you can set individual per antenna TX power levels. Refer to API documentation for more information. 5.2. RECEIVER SENSITIVITY The sensitivity of the receiver can be adjusted by three steps. Low, Nominal and High with 10dB step sizes. By default, the Nominal setting is used. 5.3. RF-PROFILE There are 3 different RF profiles which can be selected.
2019-03-08 NUR-0W1 HW implementation guide CONFIDENTIAL Version 1.0 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.

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.

DYNAMIC POWER SAVE MODE NUR-0W1 module has power save modes which can be enabled via SW API. By default, the power save is ON with depth of 100ms. Other depths are 500ms and 1000ms.
2019-03-08 NUR-0W1 HW implementation guide CONFIDENTIAL Version 1.0 8.1. CHANNEL SCANNER TBD 8.2. REFLECTED POWER MEASUREMENT 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 NUR-0W1 module set a carrier wave ON at full power and then measure the power level which is coming to receiver port. To transform the returned value into absolute power level coming in to modules RF-pin, you need to add 13 to the obtained value.
