Lowpass Filter

A Lowpass Filter (LPF), also known as a high-cut filter, is a passive RF component that passes signals below a specified cutoff frequency while attenuating all frequencies above it. At Concept Microwave, our lowpass filters feature a direct connection from input to output, passing DC and all frequencies below the specified 3 dB cutoff frequency with low insertion loss, while providing high rejection in the stopband to suppress higher-frequency interference, harmonics, and spurious signals
  • 300W High Power Lowpass Filter Operating from DC-3600MHz

    300W High Power Lowpass Filter Operating from DC-3600MHz

    The CLF00000M03600N01 miniature harmonic filter provides superior harmonic filtering, as demonstrated by the rejections levels of greater than 40dB from 4.2GHz to 12GHz. This high-performance module accepts input power levels up to 300 W, with only a Max. 0.6dB of insertion loss in the passband frequency range of DC to 3600 MHz.

    Concept offers the best Duplexers/triplexer/filters in the industry, Duplexers/triplexer/filters have been broadly used in Wireless, Radar, Public Safety, DAS

  • Lowpass Filter Operating from DC-820MHz

    Lowpass Filter Operating from DC-820MHz

    The CLF00000M00820A01 miniature harmonic filter provides superior harmonic filtering, as demonstrated by the rejections levels of greater than 40dB from 970MHz to 5000MHz. This high-performance module accepts input power levels up to 20 W, with only a Max. 2.0dB of insertion loss in the passband frequency range of DC to 820MHz.

    Applications of Low Pass Filters

     

    • Cut off high-frequency components in any system above its operating frequency range

    • 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

    • In RF transceivers, LPFs are used to significantly improve the low-frequency selectivity and signal quality
