Description

technical field

[0001] The invention belongs to the technical field of DC blockers, and in particular relates to a high-voltage-resistant low-intermodulation broadband dielectric capacitor DC blocker. Background technique

[0002] With the development of microwave communication technology, people's demand for high-power and broadband passive devices is increasing day by day. With the frequent occurrence of induced voltage in the communication system and affecting the normal operation of the system or burning the system, DC blockers are also widely used in the communication system. At present, DC blockers on the market are mainly divided into two types, one is a DC blocker with pin ceramic capacitors as the main body, this type of product cannot achieve low intermodulation, and intermodulation signals will interfere with the normal operation of the system after being connected to the system; one is A DC blocker that generates capacitance for the mechanical structure. This ty...
