  • Forum Post: Increasing Rage of TRF7960 with metal near the antenna

    Christoph80
    Hello In our device a reader with TRF7960 is used to read ISO 15693 tags, which are placed 5cm below the antenna. This works fine. But when we place another PCB 5mm above the antenna, the tags can't be read anymore. I assume that the ground plane of the PCB causes this effect. When I activate...

    Vladimir Nohava
    Hello, Given the TRF7960EVM outputs 200mW of power and that the antenna diagonal length is 2" gives a reading range of 4". I am trying to design an antenna that can read laundry tags (RF-HDT-DVBE-N2) at a distance of up to 8 inches away. I see that the read distance using 300mmX300mm...

    tdyer
    I recently purchased a TRF7970 EVM board and I'm trying to read a Fujitsu MB89R118 that it is ISO15693 compliant. The inventory command fails along standard reads and writes. I can read other ISO15693 tags. I think it may be due to the Fujitsu requiring ASK 10% only. Any sample code or suggestions...

    The information obtained from the RFID tag seems to be stored in the variable "buf", which is an array with the length 300 and declared as unsigned 8 bit. In the code (ISO15693.c) there is a comment saying that "the first UID will be stored from buf[1] upwards", but a lot of other...

    Josh- the flag IRQ is generated by the port 13 of the TRF7960???if so, I get no signal from it. sending data tells me you, and I hope that this terminal do a interruption on my micro, but it does, It don´t the rissing. Thank for all
