Abstract: A microwave component of cavity type includes an integral cavity and a microwave network circuit disposed in the cavity. The cavity has multiple enclosing walls and a chamber defined by said multiple enclosing walls. The chamber is intended for accommodating the microwave network circuit therein. A wiring slot is defined in at least one of the enclosing walls, and at least one first through hole extended through the chamber is provided on each wiring slot. The microwave component of cavity type features small size, simple structure, and wide application. Furthermore, cost may be reduced, batch production may be achieved, use of fasteners such as screws is avoided, and the passive inter-modulation products caused by fasteners are eliminated, as the microwave component is secured without any screws.
