The RF data communication band pass filter is a fixed device that filters both RF multi-level data signals and binary-level data signals. The RF data communication band pass filter comprises a low pass filtering means having a corner frequency of approximately 2900 Hertz and as high pass filtering means of approximately 340 Hertz. By using precision components the overall group delay envelope is such that both multi-level RF data signals and binary-level RF data signals are adequately filtered without substantial harmonic distortion or spectral distortion. In addition, the communication band pass filter meets the strictest of international RF data communication requirements.
