Other Parts Discussed in Thread: TRF7960

Hi, I have a TRF7960EVM. I want to increase the read range and so I would like to go for the Power amplifier. I have downloaded the application note for HF Power Amplifier (Reference Design Guide) "appnote_trf796x_pwramp_4w.pdf " from TI operating on 4W. Please let me know the part number of the power amplifier board. Also there is a 30cm X 40cm antenna used for read range of 47cm as mentioned in the application note. Kindly provide me the part number of the antenna also.

Hello,

The board was never released to market, it was for internal demonstration purpose only. However, you can make a board using the schematic and the BOM.

BR,

The 30cm x 40cm antenna referenced is from Feig Electronic.

The antenna was not from Feig - it was a custom antenna, which could be made from app notes residing here ==> http://www.ti.com/rfid/docs/manuals/appNotes/HFAntennaDesignNotes.pdf
