Abstract

The invention discloses an ultra-wideband millimeter wave high-power planar film load, and relates to the technical field of communication equipment and radio amplifiers. According to the technical scheme, a resistive film is a fan-shaped structure with one end connected with an input electrode (2) and the other end which is open-circuited, the input electrode (2) is connected with a fan-shaped resistive film through a microstrip impedance line, a single-port thin film circuit is formed based on the fan-shaped resistive film, and radio frequency signals are fed into the input electrode (2) from an input microstrip port (1). Radio frequency signals are guided to be transmitted to the open-circuit end of the fan-shaped resistive film from the tail end of the input electrode (2) by entering the range of the fan-shaped resistive film through the microstrip impedance line so that ultra-wideband matching and absorption of the radio frequency signals are realized. The load is mainly used formillimeter wave power synthesis systems, array antennas, multi-channel receivers and the like.

Description

technical field

[0001] The invention relates to an ultra-broadband high-power film load mainly used in the technical field of millimeter wave communication equipment and radio amplifiers. Background technique

[0002] The millimeter-wave load is one of the important components in the millimeter-wave circuit. It is mainly used to realize the reflection-free matching of the transmission line, and its performance directly determines the performance of the millimeter-wave circuit. It is widely used in millimeter-wave circuits such as power combining systems, antenna feed networks, and couplers.

[0003] Millimeter wave loads are mainly divided into waveguide type and planar type. The waveguide load has two structures: rectangular waveguide load and coaxial load. Among them, the rectangular waveguide load has a high rated power and is suitable for high-power application systems. The coaxial load has a small rated power and is easy to use and is suitable for millimeter wave frequ...
