Abstract

The present invention is a PCB (printed-circuit board) type band-pass filter to filter out high-frequency harmonic spurious. The band-pass filer applies the manufacturing technology of PCB. When manufacturing the circuit board of wireless communication products, the input microstrip line, circuits included in the band-pass filter such as a microstrip line with end-shorted, a microstrip line with end-opened, and an output microstrip line, etc., are disposed on the circuit board directly. Thus, without using additional high-frequency filter, the harmonic spurious with twice, three-times, and four-times frequencies generated by the nonlinear distortion of the power amplifier in the wireless communication product can be inhibited effectively. The manufacturing cost of the wireless communication product is greatly reduced, and the interference due to electromagnetic wave can be effectively reduced.
