Low pass filter has a direct connection from input to output, passing DC and all frequencies below some specified 3 dB cutoff frequency. After the 3 dB cutoff frequency the insertion loss increases dramatically and the filter (ideally) rejects all frequencies above this point. Physically realizable filters have ‘re-entry’ modes that limit the high frequency capability of the filter. At some higher frequency the rejection of the filter degrades, and higher frequency signals can appear at the output of the filter.

Applications of Low Pass Filters
• Low pass filters are used in radio receivers to avoid high-frequency interference
• In RF test laboratories, low pass filters are used to construct complex test setups
• Cut off high-frequency components in any system above its operating frequency range
• In RF transceivers, LPFs are used to significantly improve the low-frequency selectivity and signal quality
