This paper describes the principle and design of broadband matched low-pass filter. Different from the conventional low-pass filter, the input port of this filter has H matching characteristics in the passband and stopband, which can solve the problem of poor out-of-band suppression performance caused by out-of-band mismatch in the system connection of conventional low-pass filter. The whole circuit is made on a 40X 20X 0.5mm\'\' composite dielectric substrate. The experimental results show that the insertion loss of the broadband matched 3GHz low-pass filter in the band is less than 1.115dB, the out-of-band suppression is less than 40dB, and the out-of-band standing wave is less than 2.5.
