Abstract

The invention discloses a micro short circuit branch-loaded ultra-wide-band filtering attenuator. The filtering attenuator comprises a numerical control attenuation chip and an ultra-wide-band filter,wherein the numerical control attenuation chip is mounted on the ultra-wide-band filter, and a chip welding interface and a welding position are reserved on the ultra-wide-band filter; the numericalcontrol attenuation chip, a first strip line and a second strip line are mounted on the upper surface of the ultra-wide-band filter; the first strip line and the second strip line are both connected with the numerical control attenuation chip; a signal input port is mounted in one end of the micro short circuit branch-loaded ultra-wide-band filtering attenuator while a signal output port is mounted in the other end; and a first grounding end is mounted on one side surface while the first to tenth voltage control end interfaces and a second grounding end of the numerical control attenuation chip are mounted on the other side surface in sequence. The micro short circuit branch-loaded ultra-wide-band filtering attenuator is small in size, simple in structure, high in reliability, high in batch consistency, and can be applied to satellite communication, military communication occasions and corresponding circuit and communication systems.

Description

technical field [0001] The invention belongs to the technical field of integrated chip filters, in particular to a miniature short-circuit stub loaded ultra-wideband filter attenuator. Background technique [0002] In recent years, the rapid development of wireless communication, satellite military communication and other fields has put forward higher requirements for its communication electronic system. The advantages of miniaturization, high performance, low cost and easy batch processing have become important research directions in the field of electronic devices today. The performance, size and stability of microwave filters have higher and higher requirements. Many types of passive devices based on low-temperature co-fired ceramic technology, such as filters, duplexers, and power splitters, have been used in many cutting-edge defense equipment, and passive devices with integrated active chips will also be used in future electronic play an important role in the system. ...
