• Introduction

The OM5569/NT322FM evaluation and development kit is designed to provide the user with all the components and programs needed to evaluate, modify and develop the application of binary tags within the RFID sphere. This generation 2 standard kit is based on the thin-film silicon MMIC process and provides full support of the EPC global and currently most widely used standard, the ISO-18000-6C (UHF Gen2) protocol. It provides high-performance near-field communication as well as a highly flexible 8-channel multi-gate transceiver design that is ideal for RFID applications.

• Hardware and Design

The OM5569/NT322FM protocol is based on an eight-channels receiver with two separate receivers and transceivers. The first contains a receiver transceiver with a two-level gain control for optimum performance in both poor and excellent communication conditions. The receiver runs at a frequency of 915MHz and has a 6 dBi omni-directional antenna as standard. The second transceiver is based on a broadband (up to 24GHz) receiver amplifier for an improved signal-to-noise ratio, and a low-power switching channel for optimum power. The multi-gate transceivers enable stand-alone operation without the need for an external control unit.

The kit comes with the OM5569/NT322FM board, which has been designed to accommodate various board types, including the CBB (Contactless Batteryless) and the HAT (Harvest-and-Transmit) boards. The OM5569/NT322FM is powered by either the 3V or 5V DC supply and is compatible with a wide range of RFID readers and remote antennas. It is suitable for physical applications such as security (e.g. toy authentication), accommodation (e.g. access control), laboratory, and hobbyist applications.

• Applications and Uses

The OM5569/NT322FM kit has several applications and uses. It has been designed to provide the user with a comprehensive suite of tools to evaluate, modify and develop the application of RFID tags for various applications. It is suitable for use in research projects, laboratory, and hobbyist applications, and can also be used for authentication, location, tracking, as well as security.

The OM5569/NT322FM can be used in several distinct modes. It can be used as part of a system for near-field communication or for tag and/or reader authentication. The kit allows the user to evaluate the performance of a tag and/or reader system with respect to the various parameters such as bit rate, power, sensitivity, and coverage. It can also be used as a remote access system, providing access control to users by using the UHF frequencies, allowing them to communicate with each other. Furthermore, the OM5569/NT322FM can be used as a base station for local RFID projects such as time- and attendance-tracking systems. It is also compatible with a range of sensors and transducers, making it ideal for applications such as infrared, gas and humidity sensors.

• Conclusion

The OM5569/NT322FM is a powerful evaluation and development tool that is suitable for near-field communication, authentication, location, and tracking. With its 8-channel multi-gate transceiver design, it is ideal for use as a base station in local projects, as well as providing a comprehensive suite of tools for evaluating, modifying and developing applications of RFID tags. It is highly adaptable and compatible with a range of antennas, readers, sensors and transducers, making it a versatile and powerful choice for numerous applications.
