    Thread Summary
    
                The user inquires about using the MAX2830 for wireless audio applications, specifically if it can handle 0-20kHz analog signals. The final answer confirms the TX path can handle audio frequencies, but the RX path's HPF with a 100 Hz corner frequency will attenuate low-frequency signals. The support engineer advises against using the MAX2830 for this application due to potential distortion, as it is optimized for 802.11 standards.

    Hello,
    

    I plan on using the MAX2830 for a custom TX/RX pair for wireless audio applications, but im concerned if the chip can accept 0-20kHz on its TX pins. Does anyone with experience  using this chip know if I can feed low frequency analog into it?

      The MAX2830 has a LPF in the TX path and HPF/DC Offset Correction in the RX path. The TX should have no issues handling signals in the audio range, but the RX path HPF has a 100 Hz corner frequency, which will attenuate signals in said range.
       
      Even if the TX/RX paths could handle those frequencies, I do not recommend using the MAX2830 for this application, as it is intended/optimized for use with the 802.11 standard. Any audio signal you feed to this part may end up distorted as a result.
