The invention discloses a minitype WiFi band-pass filter which is applicable to various handy terminal communication systems, including the Bluetooth system and the Wireless Local Area Network (WLAN) system. In addition, the LTCC technology is adopted, a special structural design is employed, so that dimension of the minitype WiFi band-pass filter is minimized. In the invention, the minitype WiFiband-pass filter realized by the low temperature co-fired technology can realize inband low insertion loss and out-of-band high-frequency choke and especially has the characteristic of high choke on image frequency; in addition, the filter has the advantages of high quality factor, high stability, suitability for mass production, low cost and the like and provides preconditions for miniaturizing electronic products.
