P wave band higher-order harmonic suppression micro low pass filter

The invention relates to a P wave band higher-order harmonic suppression micro low pass filter. The low pass filter comprises a 50-ohm impedance input/output interface which is suitable for surface mounting, and three inductors, four ground capacitors, two zero capacitors and input and output inductors realized by using a lumped parameter strip line structure. The structures are realized by adopting a multilayer low-temperature co-firing ceramic process technology. The low pass filter has the advantages of high pass band selectivity, deep harmonic suppression, small size, light weight, high reliability, high electric performance, high phase frequency characteristic linearity, high temperature stability, high electric performance batch consistence, low cost, batch production and the like, and is particularly suitable for wireless communication handheld and portable terminal products such as radars, communication, rocket mounting, machine mounting, bullet mounting, spaceships, individual soldier mobile communication terminals and the like, occasions with severe requirements on size, weight, electric performance, reliability and the like, and corresponding frequency band systems.
