High frequency mobile phone dielectric filter duplexer having dielectric block with upper surface having deposited resonant holes and side wall mounted reception/transmission wires

摘要

The dielectric duplex filter has a dielectric block (101) with an upper surface (103). Metal is deposited on the side walls (105) and top surface. There are filter zones with resonant holes (107) , and open zones (125). There are reception wires (112b) and transmission and antenna wires (112c) formed on the side wall surface.
