A kind of eutectic carrier and microwave device

Abstract

The invention relates to a eutectic carrier and a microwave device, which belongs to the technical field of microwave devices and solves the problems that an existing microwave device is low in spaceutilization rate and low in resonance frequency, and cannot meet requirements of an electronic device for maintainability and space utilization rate of a small-sized microwave device. An end portion and a middle portion of the I-shaped eutectic carrier provided by the invention are respectively provided with fixed hole positions and a microwave component, and the microwave component comprises a microwave amplifier, a numerical control attenuator and a feed insulator, and ceramic chips are disposed on both sides and at the middle of the microwave amplifier and the numerical control attenuator.The I-shaped eutectic carrier is simple in outer shape structure, the cavity size of the eutectic carrier is reduced and the possibility of cavity resonance is reduced, and the feed insulator can be installed on a retractable position under the premise of ensuring line-shaped arrangement of the microwave component, the space ratio of installation of the eutectic carrier can be effectively reduced,and the I-shaped eutectic carrier is especially suitable for a miniaturized microwave device with high maintenance and space ratio requirements.

Description

technical field [0001] The invention relates to the technical field of microwave devices, in particular to a eutectic carrier and a microwave device. Background technique [0002] At present, the assembly methods of bare chips are mainly divided into eutectic, eutectic solder brazing, other solder brazing and polymer bonding. The eutectic carrier can avoid reducing the reliability of chip assembly due to the difference in expansion coefficient between the cavity and the chip. At the same time, as a detachable platform, it also enhances the flexibility of chip assembly and the maintainability of the device, and is widely used in miniaturized microwave devices. [0003] Due to the structure and mounting method of the eutectic carrier in the existing microwave device, the microwave device cannot realize the layout requirements of two low-noise receptions and one digital control attenuation output, the space utilization rate is low and the resonance frequency is low, which canno...
