TRF7961RHBT Frequently Asked Questions (FAQs)

  • The recommended antenna design is a dipole or a patch antenna with a impedance of 50 ohms. The antenna should be tuned to the operating frequency of 13.56 MHz and have a gain of around 2 dBi.
  • The TRF7961RHBT can be configured for different RFID protocols by setting the appropriate registers and using the correct modulation and coding schemes. Refer to the application notes and the datasheet for specific configuration details.
  • The maximum distance achievable with the TRF7961RHBT depends on the antenna design, the power output, and the environment. Typically, a distance of up to 10 cm can be achieved with a standard antenna design.
  • The TRF7961RHBT has built-in support for anti-collision protocols such as ISO/IEC 14443-3 and ISO/IEC 15693-3. The device can detect collisions and perform anti-collision algorithms to resolve them.
  • The power consumption of the TRF7961RHBT depends on the operating mode and the frequency of operation. The device has a typical current consumption of 100 mA in transmit mode and 10 mA in receive mode. Power consumption can be optimized by using power-saving modes, reducing the transmit power, and optimizing the antenna design.
