TRF371125: 2.4G 802.11 preamble detection

Part Number: TRF371125

Hi all,

Is TRF371125 able to demodulate the preamble signal of 802.11G (802.11g ERP-DSSS/CCK PPDU frame) which consists of D-BPSK and OFDM?
My customer would like to use TRF371125 to output the trigger pulse signal synchronized with the reception timing of the preamble and the beacon.


  • Yes, the RF band of interest (2.4GHz) falls within the demodulator’s frequency range of operation. However, this demodulator will only shift the detected signal down, you will need to make sure that the ADC, FPGA, etc… in your system can decode the data to make use of it.
