A High Voltage and Low Intermodulation Broadband Dielectric Capacitive DC Blocker

Abstract

The invention discloses a high-voltage-resistant low-intermodulation wide-band dielectric capacitive direct-current blocker in the technical field of direct-current blockers, which can take both wide-band and low-intermodulation functions into consideration, and greatly improves the influence of induced voltage on communication systems. It includes a housing, the housing is fixedly connected to the first connection block and the second connection block respectively, and a first ceramic capacitor piece and a second ceramic capacitor piece are arranged between the first connection block and the second connection block ; The first ceramic capacitor is flexibly connected to the first inner conductor and the second inner conductor respectively; The first inner conductor is fixedly connected to the first connection device, and the first connection device is fixed to the first connection block connection; the second inner conductor is fixedly connected to the second connection device, and the second connection device is fixedly connected to the second connection block; there are multiple second ceramic capacitors, each of the second ceramic The capacitor sheets are flexibly connected to the first connection block and the second connection block respectively.

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...

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 type of product cannot achieve a wide frequency band. A DC blocker cannot meet the frequency band required by the entire system, and the size of the DC blocker in different frequency bands varies greatly.
